Starting with SharePlex 8.6.3 and up, it is now possible to have Export process compress the data it sends to the target. This is done by setting the parameter as follows on the source sp_ctrl:
sp_ctrl>set param SP_XPT_ENABLE_COMPRESSION 1
The parameter takes effect once the Export is bounced. This article delves on the advantages that come with the compression feature.
The following are some of the obvious advantages of using compression:
1. More efficient data transfer as the quantum of data transported is reduced, and it is faster even with factoring the overheads involved in compression of data (on source) and decompression of data (on target).
2. It reduces the latency at target.
3. If bandwidth is a constraint, the compression offers a way around such limitation.
4. It reduces the cost associated with WAN as less bandwidth is needed.
5. An added advantage is, the compressed data offers an additional layer of security as any anyone outside of SharePlex will need additional tool to uncompress the data to be able to read it, if the data packet sent from source to target gets intercepted before it reaches the target.
Here is the description of the parameter as taken from SharePlex Reference Guide:
