Does PGStrom calculate relational comparisons? I prefer index calculation and comparison be executed on the GPU.

I have stumbled upon PGStrom.

It seems one could infer that it will calculate index comparisons, but the claim doesn't seem to be made explicitly, and I stopped assuming years ago.

As an example, would PGStrom calculate this where condition:

SELECT * FROM some_parent, some_child 
    WHERE some_parent.bigint_id = some_child.parent_bigint_id


Does PGStrom calculate relational comparisons?
no, pgstrom cannot do that. it only able to scan relations - it is not able to join.
what you an do is pack an operator into a GPU routine but = is not a good candidate for that.
