System Requirements and Conditions of Support When Replicating from Oracle

This chapter contains the requirements when capturing from an Oracle database and replicating to supported target databases.

Prerequisite: At least the minimum level of supplemental logging must be enabled. Some SharePlex features may require PK/UK supplemental logging to be enabled.

Oracle source basics

This section contains the requirements for an Oracle database as a source when capturing from an Oracle database and replicating to supported target databases.

Supported operating systems

The following operating systems are supported for capture from a supported Oracle database and replication to an Oracle target database. For a list of supported source and target databases for Oracle capture, see Supported Source and Target Combinations.

SharePlex supports only the 64-bit version of the listed operating systems.

Supported operating systems via native installation:

Note:  SharePlex supports the following operating systems and only where the version matches the Oracle certified platforms. For example, Oracle 19c supports Linux 7 and later, therefore installation of SharePlex on a system with Oracle 19c is supported only on Linux 7 and later.

  • AIX 7.1, 7.2, and 7.3

  • CentOS Linux 7.x and 8.x

  • HP-UX 11.31 Itanium

  • Oracle Linux (RHCK and UEK) 7.x and 8.x

  • Oracle Solaris SPARC 11.4

  • Oracle Solaris x86 11.3 and 11.4

  • RHEL 7.x and 8.x

  • SuSE SLES 12.x and 15.x

Supported operating systems via remote replication:

All platforms listed above, plus Windows Server 2016 and 2019, are supported via remote replication.

Important! SharePlex 11.0 can only be installed on Unix and Linux platforms.

A SharePlex version that can be installed on Windows will be supported in a future version. Customers with database platforms that run on Windows should consult the Installation and Setup for Remote Capture and Run database setup for Oracle remote capture sections from the Installation and Setup Guide for an Oracle Source for the Capture process and the Replicate to a remote target system section from the SharePlex Admin Guide for the Poster process that describe support for remote replication scenarios that may address your particular platform requirements.

Supported versions

SharePlex supports the Standard and Enterprise Editions of Oracle 12cR1, 12cR2, 18c, and 19c.

Notes:
  • Unless specified, Oracle, RAC, and ASM are supported for the same versions.
  • SharePlex supports only the 64-bit version of Oracle Database
  • In addition to the Supported Operating Systems for Oracle and the Supported Cloud Platforms for Oracle, the Oracle versions listed above are also supported when running on an Oracle Exadata Database Machine.
  • Amazon RDS for Oracle 12cR1 (supported 12cR1 versions are 12.1.0.2.v7 or later) and 19c. Support for Oracle features on Amazon RDS is limited to the default option groups: default:oracle-ee-12-1, default:oracle-ee-19, and default:oracle-se2-19.

Supported cloud platforms

Oracle Cloud Infrastructure

  • Oracle Exadata Cloud Service (ExaCS)
  • Oracle Exadata Cloud@Customer (ExaCC)1
  • Oracle Database Cloud Service (DBCS)
  • Oracle Compute (IaaS) Virtual Machines and Bare Metal

Amazon Web Services

Oracle source basic conditions of support

Non-supported Oracle features

This is a list of commonly used Oracle features which SharePlex does not replicate and are not listed elsewhere in this document. Since both Oracle and SharePlex continually change and improve, this list of exclusions cannot be considered complete. Unless an item is stated here as being supported, assume that SharePlex does not replicate it.

Object/operation/feature Not supported
Oracle operations Operations that do not appear in the redo logs. This includes any DML or DDL not in the redo logs, and also PL/SQL packages which do not write results to the redo logs, for example, dbms_shared_pool.keep and related packages.

dbms_scheduler.create_job

This object is not supported.

Flashback

SharePlex does not support the Oracle Flashback Table feature. If the SP_REPLICATE_ALL_DDL parameter is enabled (value of 1), SharePlex may try to replicate the flashback DDL, which will return an error. To perform Flashback Table on a table that is in replication, use the following procedures to work around this issue:

  1. Remove source objects from replication
  2. Perform the flashback
  3. Add or change objects in an active configuration
Additional information about data types

Notes about open target data type support 

  • Replication of SecureFile LOBS to non-Oracle databases is supported except if the storage specification includes any level of compression, encryption, and/or deduplication.
  • Replication of LOB operations generated by dbms_lob are not supported when replicating to non-Oracle targets.

  • SharePlex applies replicated Oracle data to the target according to the data type of the target column, rather than mapping to a default data type. Corresponding source and target columns must contain compatible data types to ensure successful DML operations.
  • If the precision or size of the target data type is not large enough for the data being replicated, the target database may truncate or round the data when SharePlex applies it.

SharePlex does not support the replication of data from Oracle to open targets for the below Extended Data Types: 

  • VARCHAR2 (4000-32767)
  • NVARCHAR2 (4000-16383)
  • RAW (2000-32767)

Supported Oracle database version/s

SharePlex supports the Standard and Enterprise Editions of Oracle 12cR1, 12cR2, 18c, and 19c for replicating the OLTP compressed data.

Supported objects and operations for DML replication

SharePlex supports DML operations on tables and sequences, with some conditions. DML can be replicated from an Oracle source to an Oracle or an open target.

Note: Replication to targets with a different character set is supported, with limitations. When posting to open target databases, XML files and JMS, SharePlex supports only UNICODE and US7ASCII on the target, but conversion can be performed by an Oracle client installed on the target system. For full details, see the Preinstallation Checklist in the SharePlex Installation and Setup Guide.

Tables

SharePlex supports the following DML operations on tables:

  • INSERT, UPDATE, DELETE, COMMIT, ROLLBACK
  • Direct-path loads (SQL*Loader) (INSERT AND FULL ROLLBACK).

Note: Replication of partial rollbacks of DLOADs is not supported.

The target table must support the column types that are being replicated from the source Oracle table.

SharePlex supports the following table types for DML operations:

Supported table type*

Conditions of Support

Regular Oracle tables

None

Index-organized tables

SharePlex does not support:

  • Replication to/from index-organized tables that contain LOB or VARRAY columns
  • Replication from a non-index-organized table to an index-organized table
  • SharePlex hash-based horizontal partitioning of index-organized tables

Partitioned tables

None

Views

None

Materialized views

SharePlex does not support replication from a materialized view to a materialized view. SharePlex can replicate the underlying table of a materialized view to a regular target table.

SharePlex does not support the following table types:

  • Replication to/from nested tables
  • Replication to/from clustered tables

*SharePlex does not support the following for any table type:

  • Replication to/from Identity columns.
  • Replication of rows changed by 'UPDATE WITH CASE' syntax.
  • Replication of rows in which data exceeds 319 KB in size, excluding LOB and LONG columns
  • Replication of external tables or tables with external partitions

Sequences
  • Transactional changes to Oracle sequences can be replicated only from Oracle to Oracle.
  • To replicate transactional changes to sequences, the supplemental logging of primary and unique keys must be enabled at the database level, or you must enable supplemental logging for primary keys on the sys.seq$ table.
Secured and compressed objects

SharePlex supports DML operations on secured or compressed objects as described in the following table. See "Conditions of support" following this table for additional information.

Secured/Compressed Object Can be replicated to:  
DML on tables encrypted by Oracle Obfuscation Toolkit All target types  

DML on tables with Transparent Data Encryption (TDE)1

All target types  

DML on Oracle Label Security (OLS)2

All target types  

DML on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3

All target types  

Direct Load (DLOAD) on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3

All target types  
Conditions of support

1. Conditions of support - TDE

SharePlex supports Tablespace Encryption and Column Encryption, both source and target.

The SharePlex  copy/append command does not support TDE.

TDE is not supported for sources on RDS.

SharePlex only supports the AES and DES encryption algorithms.

2. Conditions of support - OLS

By default, SharePlex cannot process rows that are protected by OLS (Oracle Label Security) because users granted DBA privileges (like SharePlex) do not have enough privileges to access those rows. However, if privilege is granted from the OLSSYS user, SharePlex can support OLS. SharePlex was tested under the following OLS configuration:

  • The SharePlex user was granted full privilege to the objects in replication.
  • Test tables with OLS security were created.
  • Data was replicated using INSERT, UPDATE, DELETE, ROLLBACK, and TRUNCATE operations, and ALTER TABLE to add and drop columns.

Note: If the OLS policy data label column is defined as hidden, the data in that column cannot be replicated by SharePlex.

3. Conditions of support - compression

For HCC compression: SharePlex does not support query low compression. Supported types of compression are query high, archive low and archive high.

For Advanced Row (OLTP) Compression: Under certain conditions, Oracle does not provide enough information in the redo log for SharePlex to replicate a DML operation on a OLTP compressed object. Testing of OLTP compressed objects is advised.

Oracle to open targets DDL support

SharePlex provides default and optional DDL support.

Note: ALTER TABLE to ADD COLUMN and ALTER TABLE to DROP COLUMN are supported on Basic, Advanced Row (OLTP) Compression, and HCC compressed Oracle objects for replication to all Oracle and open targets.

SharePlex does not support:

  • ANALYZE TABLE and ANALYZE INDEX
  • DDL to ALTER TABLE ADD OVERFLOW to an IOT in replication
  • DDL operations issued by the SharePlex database user
  • DDL to ALTER INDEX to an IOT in replication

SharePlex provides limited DDL support for replication from Oracle to open targets. The involved objects must be listed in the active configuration file explicitly or with a wildcard. There is no optional DDL support for replication from Oracle to cross platforms.

The default Oracle to open target configuration is represented by the following parameter setting:

SP_OCT_REPLICATE_DDL=3

See "Table Notes" following this table for additional information.

Supported object Supported Operation
Table and IOT Truncate1
Alter table add column2
Alter table drop column
Table Notes:
  • TRUNCATE TABLE is not supported from Oracle compressed objects to open targets.

  • The default mappings of Oracle data types to their open target counterpart for replicated ALTER TABLE ADD COLUMN DDL are shown in the "Supported Data type" section of the respective target. When SharePlex adds the column, it defines it with the default data type. This mapping applies to the entire configuration (not per table).

Supported data types

SharePlex supports the following Oracle data types for replication to Oracle targets. See the Conditions of support for additional information.

  • ANYDATA 1
  • B-FILE
  • BINARY DOUBLE 7
  • BINARY FLOAT 7
  • BLOB 2
  • CHAR
  • CLOB 2
  • DATE
  • INTERVAL
  • LONG RAW2
  • LONG 2
  • NCHAR
  • NCLOB 3
  • NUMBER
  • NVARCHAR2 8
  • RAW 8
  • ROWID
  • SDO_GEOMETRY
  • TIMESTAMP
  • TIMESTAMP WITH LOCAL TIME ZONE
  • TIMESTAMP WITH TIME ZONE
  • UDT (User Defined Type)5
  • UROWID
  • VARCHAR
  • VARCHAR2 8
  • VARRAY collectors
  • XMLTYPE 4

Note: SharePlex supports columns that are defined as INVISIBLE.

Conditions of support

1. Conditions of support - ANYDATA

  • Replication of ANYDATA is supported, except when it contains a UDT or the storage is defined as SecureFile LOB with compression. SecureFile LOB without compression is supported. Only the following data types within ANYDATA are supported by SharePlex:

    • CHAR
    • DATE
    • NUMBER
    • RAW
    • VARCHAR
    • VARCHAR2
    • TIMESTAMP
  • A data type within an ANYDATA type must be in-row (inside the column data). Oracle encapsulates the ANYDATA type as an in-row secure file LOB. If the encapsulated data is longer than the length allowed for an in-row LOB, that data appears as out-of-row LOB data. SharePlex assumes that the encapsulated data always appears as in-row LOB.

2. Conditions of support - LONG and LOB (BLOB, CLOB)

  • Any table that contains a LOB or LONG should have a primary key or unique key defined on it. If a table does not have a key, SharePlex builds its own key from all of the columns except LONGs or LOBs. If a LOB or LONG is the only difference between two rows that otherwise satisfy the Post WHERE clause, SharePlex cannot guarantee that the correct row will be updated.
  • SharePlex supports SecureFiles LOBs as follows:

    • Logging must be enabled.
    • SharePlex supports uncompressed SecureFiles LOBS and SecureFiles LOBS with high or medium compression
    • SecureFiles LOBS are not supported when the storage specification includes encryption and/or deduplication.
  • SharePlex does not support LONG and LONG_RAW data types in a configuration where transformation or conflict resolution are performed.

3. Conditions of support - NCLOB

NCLOBs are not supported by Compare/Repair if the source and target have different character sets.

4. Conditions of support - XMLTYPE

SharePlex supports the replication of XMLTYPE stored as CLOB and BINARY. SharePlex does not support XMLTYPE stored as OBJECT RELATIONAL. Additionally, the following applies:

  • XMLTYPE stored as BINARY is not supported when the storage is defined as SecureFile LOB with compression. SecureFile LOB without compression is supported.
  • Binary XMLTypes are not supported by Compare/Repair when the source and target character sets are different and require character set conversion.
  • Compare/Repair does not support comparison of XMLTYPE when the source and target have different storage clauses. Compare/Repair only supports compare/repair when source and target are both stored as BINARY or both are stored as CLOB.

5. User-defined types

SharePlex does not support abstract data types and VARRAYs in a configuration where the SharePlex conflict resolution feature is performed.

NOTE: SharePlex replicates tables with the UDT fields in the base type ONLY. In case of columns containing multiple subtypes, replication is applicable only for base type fields.

6. Conditions of support - general

If the precision or size of the target data type is not large enough for the data being replicated, the data may be truncated or rounded by the database when applied.

7. Conditions of support - Extended Data Types

  • Extended Data Types are not supported for the Copy command.
  • Extended Data Types are not supported on a key column. The keys that do not support the Extended Data Types include:
    • Primary key on the Oracle table
    • Unique key on the Oracle table
  • Horizontal partitioning is not supported by tables containing the Extended Data Type columns.
  • SharePlex does not replicate data with Extended Data Type when target type is JMS Message Queues, File output (XML, JSON, SQL), Event Hubs, or Kafka.

Supported operations and objects for DDL replication

SharePlex provides default and optional DDL support.

Note: ALTER TABLE to ADD COLUMN and ALTER TABLE to DROP COLUMN are supported on Basic, Advanced Row (OLTP) Compression, and HCC compressed Oracle objects for replication to all Oracle and open targets.

SharePlex does not support:

  • ANALYZE TABLE and ANALYZE INDEX
  • DDL to ALTER TABLE ADD OVERFLOW to an IOT in replication
  • DDL operations issued by the SharePlex database user
  • DDL to ALTER INDEX to an IOT in replication
DDL on objects listed in the active configuration file

SharePlex supplies default and optional DDL replication for objects whose names are listed in the configuration file explicitly or by wildcard. See "Conditions of support" following this table for additional information.

For details about the controlling parameter, see the SharePlex Reference Guide.

Conditions of support
  1. ALTER TABLE has the following conditions of support:
    • ALTER TABLE DDL that involves multiple tables, such as EXCHANGE PARTITION between tables, requires all tables involved to be in replication.
    • Default DDL support for ALTER TABLE on partitions/subpartitions applies to user-named interval partitions/subpartitions. For system-named (system generated) interval partitions/subpartitions, SharePlex supports only ALTER TABLE to DROP and TRUNCATE the system-named partitions. To enable support for DROP and TRUNCATE of system-named partitions, set the SP_OCT_TRUNC_PARTITION_BY_ID parameter to 1, and ensure that both source and target are updated to SharePlex version 8.6.4 or later. NOTE: This requirement has changed from previous SharePlex releases in that the parameter must now be set regardless of the Oracle version, including for Oracle 12.2 and later.
    • SharePlex does not support TRUNCATE of a system-generated sub-partition if the sub-partition is empty. In such cases, Post stops with error SP-OPO01002. To configure Post to ignore this error, stop Post, set the SP_OPO_CONT_ON_ERR parameter to 1, and add error number SP-OPO01002 to the top of the oramsglist file. See the SharePlex Reference Guide for more information about this parameter.
  1. For CREATE TABLE AS SELECT, SharePlex supports the following data types: LONG, DATE, RAW, LONG RAW, ROWID, LONG VARCHAR, CHAR, CLOB, BLOB, CFILE, BFILE, TIMESTAMP, INTERVAL YEAR TO MONTH, INTERVAL DAY TO SECOND, VARCHAR2, NUMBER, and ANYDATA.
  2. For CREATE MATERIALIZED VIEW the following applies:

    • SharePlex supports the following data types for CREATE MATERIALIZED VIEW: LONG, DATE, RAW, LONG RAW, ROWID, UROWID, LONG VARCHAR, CHAR, CLOB, BLOB, CFILE, BFILE, TIMESTAMP, INTERVAL YEAR TO MONTH, INTERVAL DAY TO SECOND, VARCHAR2, NUMBER, and ANYDATA. SharePlex does not support ALTER MATERIALIZE VIEW.
    • SharePlex converts a CREATE MATERIALIZED VIEW to a CREATE TABLE, applies the CREATE TABLE to the target, and then replicates the DML that populates the view. SharePlex does not replicate materialized views to materialized views.
  3. To replicate sequences, the supplemental logging of primary and unique keys must be enabled at the database level, or you must enable supplemental logging for primary keys on the sys.seq$ table.

  4. Amazon RDS restricts DBA users from issuing the GRANT command. Because SharePlex runs as the DBA user, SharePlex cannot replicate GRANT to or from an RDS database.

DDL on objects not listed in the active configuration file

SharePlex provides expanded DDL support for Oracle objects that are not listed in the configuration file. SharePlex replicates the DDL statements for these objects, but does not maintain synchronization of the objects through DML replication. Expanded DDL replication is optional and is enabled with the following parameter setting:

SP_OCT_REPLICATE_ALL_DDL=1

Note: Expanded DDL replication supports not only tables and sequences but also a wide range of other objects such as procedures, functions, users, and views, which are not part of replication. Some of these objects may have underlying objects that are in replication. In those cases, Expanded DDL replication applies to the underlying objects in replication, as well as to the object that is not in replication.

Oracle to Snowflake replication

SharePlex supports replication from Oracle to Snowflake, according to the details below.

Supported operating systems

SharePlex replicates remotely to Snowflake. Remote replication from the following operating systems is supported:

Red Hat Linux version 7.x, 8.x

Note: SharePlex Snowflake supports only the 64-bit version of the listed operating systems.

Supported target versions and ODBC requirements

Snowflake 6.31 Enterprise, Community version

ODBC driver requirement: Snowflake 2.24.2

Limitations:

The following ODBC driver related limitations are observed while replicating data from Oracle to Snowflake:

  • The following technical issues are identified with the Snowflake driver. Hence, we recommend you use the Snowflake ODBC Driver version 2.24.2.

    • Connection timeout issue with Snowflake ODBC Driver v2.24.3 and above

    • With Batch transactions, Snowflake can display Schema Not Found error with Snowflake ODBC Driver v. 2.25.4 and above.

Supported data types

SharePlex supports the following data types for replication from Oracle to Snowflake:

Oracle Snowflake
CLOB TEXT
NUMBER INT, INTEGER, NUMBER
CHAR(n) VARCHAR(n)
CLOB VARCHAR(n)
NCHAR CHAR(n)
VARCHAR2(n) VARCHAR(n)
CLOB VARCHAR(n)
NCLOB TEXT
CLOB VARCHAR(n)
LONG TEXT
BLOB BINARY, VARBINARY
RAW(n) VARBINARY
LONGRAW VARBINARY
BINARY_FLOAT REAL
NUMBER SMALLINT
NUMBER BIGINT
NUMBER NUMERIC, DECIMAL
DATE DATE
BINARY_DOUBLE DOUBLE PRECISION
TIMESTAMP TIMESTAMP
TIMESTAMP_TZ TIMESTAMP_TZ

Note: It is anticipated that the Snowflake DB's default "HEX" format for binary type will be maintained for Oracle binary to Snowflake binary data type replication. Since source Oracle DB binary data is stored only in "HEX" format, Shareplex does not guarantee data integrity for any other format.

Conditions of support
  • Char(n) data type - In Oracle, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses  VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) Oracle column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target DB.

  • Binary & Text data types - Snowflake Binary & Text data types have size limitation of 8 MB, so Oracle’s advance Data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.

Oracle Data type Max Size Snowflake Data type Max Size
LONG 2 GB TEXT 8 MB of unicode chars
CLOB 4 GB TEXT 8 MB of unicode chars
LONGRAW 2 GB BINARY or VARBINARY 8 MB
BLOB 4 GB BINARY or VARBINARY 8 MB

See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

Supported operations and objects for DML replication

SharePlex supports DML operations on tables, with some conditions. DML can be replicated from an Oracle source to a Snowflake target.

Tables

SharePlex supports the following DML operations on tables when replicating data from an Oracle source to the Snowflake target:

  • Singular and bulk operation - Insert with key(s)/ non key(s)

  • Singular and bulk operation - Update with key(s)/ non key(s)

  • Singular and bulk operation - Delete with key(s)/ non key(s)

Limitations:

The following DML operations related limitations are observed while replicating data from Oracle to Snowflake:

  • Slowness while performing DML operations

    • Single Insert: Frequent commits and rollbacks can cause slowness in replication.

    • Batch Inserts: Insert with advance data types [target Snowflake data types: TEXT and BINARY] can cause significant slowness in replication for data with plain text or binary JSON and XML.

    • Single Update and Delete : Frequent commits and rollbacks can cause slowness.

    • Batch Update and Delete: The Snowflake ODBC driver does not support batching of transactions. It can cause significant slowness in replication.

For additional information, see Supported Operations and Objects for DML Replication.

Supported DML operations

SharePlex supports DML operations on tables. DML can be replicated from a PostgreSQL source to an Oracle target.

Tables

SharePlex supports the following DML operations on tables:

  • Singular and bulk operation - Insert

  • Singular and bulk operation - Update with key(s)/ non key(s)

  • Singular and bulk operation - Delete with key(s)

  • Above operations with rollback/savepoint

The target table must support the column types that are being replicated from the source PostgreSQL table.

Limitation: In PostgreSQL to Oracle replication, in the source database table and column names are created in lower case by default, and in the target database they are created in upper case. In such a case, if we configure such tables in replication with the source table name in lower case with a double quote and the target table name in upper case with quotes in the configuration file, in the Post process, while creating a query, the table name is used in upper case as specified in the configuration file, but column names are used in lower case by default. Hence, this query fails in execution as the target table contains column names in capital letters.

The scenario will work fine if the target table or column name is created in lower case using double quotes in the database and the target table name is specified in small case in the configuration file.

Conditions of support
  • Char(n) data type - In PostgreSQL, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses  VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) PostgreSQL column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target database.

  • Text data types - Snowflake Text data types have size limitation of 8 MB, so PostgreSQL’s TEXT data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.

PostgreSQL Data type Max Size Snowflake Data type Max Size
TEXT unlimited TEXT 8 MB of unicode chars

See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

Supported operations and objects for DML replication

SharePlex supports DML operations on tables, with some conditions. DML can be replicated from an PostgreSQL source to a Snowflake target.

Tables

SharePlex supports the following DML operations on tables when replicating data from an PostgreSQL source to the Snowflake target:

  • Singular and bulk operation - Insert with key(s)/ non key(s)

  • Singular and bulk operation - Update with key(s)/ non key(s)

  • Singular and bulk operation - Delete with key(s)/ non key(s)

Limitations:

The following DML operations related limitations are observed while replicating data from PostgreSQL to Snowflake:

  • Slowness while performing DML operations

    • Single Insert: Frequent commits and rollbacks can cause slowness in replication.

    • Batch Inserts: Insert with advance data types [target Snowflake data types: TEXT and BINARY] can cause significant slowness in replication for data with plain text or binary JSON and XML.

    • Single Update and Delete : Frequent commits and rollbacks can cause slowness.

    • Batch Update and Delete: The Snowflake ODBC driver does not support batching of transactions. It can cause significant slowness in replication.

For additional information, see Supported Operations and Objects for DML Replication.

Supported operations and objects for DDL replication

SharePlex does not support DDL operations and objects when replicating data from an PostgreSQL source to a Snowflake target.
