Subject hawq_rm_stmt_vseg_memory and hawq_rm_nvseg_perquery_perseg_limit
Date Fri, 20 Jan 2017 13:11:32 GMT
Why is there a limit of 16GB for hawq_rm_stmt_vseg_memory?  A cluster with
256GB per node and dedicated for HAWQ may certainly want to utilize more
memory per segment.  Is there something I'm missing regarding statement
memory?

Secondly, does the number of vsegs for a query get influenced by the
statement memory or does it just look at the plan and
hawq_rm_nvseg_perquery_perseg_limit?
