Does PGStrom calculate simple index comparisons?

[ghost]

kaigai,

Thank you for creating this amazing module!

I have two questions:

1. Does PGStrom also calculate simple relational comparisons? Crosspost for details: http://dba.stackexchange.com/questions/77951/does-pgstrom-calculate-index-comparisons

2. Have you considered expanding this to index creation?

Again, can't thank you enough!

Sorry for my late response.

Yes, PG-Strom also suggest the core planner an alternative execution path that utilizes
GPU devices for simple relational comparisons also. However, its cost is usually expensive
than built-in index-scan. In the result, GpuScan shall not replace IndexScan.

Regarding to the index creation, I don't have plan to enhance the coverage of PG-Strom
to DDL region, not only DML region.
