Question/Problem Description
Is it possible to improve the data transfer speed between OpenAccess Client and OpenAccess Server ?
Steps to Reproduce
Clarifying Information
Error Message
Defect Number
Enhancement Number
Cause
OpenAccess client server protocol works as below for complete execution of the query and fetch the results.
1. Client sends request packet for query execution
2. Server initiates the query execution and replies with a response packet with the result description (result column information)
3. Client sends request packet to fetch the results
4. Server will send response packet with results that can be accommodated in ~32K network buffer and indicates if more results are available
5. Client repeats request packet to fetch remaining results
6. Server will send response packet with results that can be accommodated in ~32K network buffer and indicates if more results are available
Steps 5 & 6 will repeat until all results are returned

So performance of query needs to take into consideration the overhead of multiple packet exchanges between client and server.

Currently OA does not expose an option for tuning the network buffer size and does not use compression on the network buffers.
