Re: session paritioning in tpt script

Not certain what you mean by "session partitioning". You can use SERIALIZE ON (a subset of) Primary Index columns in the APPLY statement, so that rows with the same PI will be directed to the same session.


Tuning STREAM usually starts with making sure you don't have an issue with blocking (SERIALIZE can help there) and adjusting Pack and number of sessions.
