James Taylor commented on PHOENIX-2163:
---------------------------------------
We want to measure the *performance* of doing the EXPLAIN. The *.out logs what
the explain plan is, but the missing part is how long it takes.
So you'd want to add "EXPLAIN " in front of the queries that are running when
Phoenix is used and "EXPLAIN PLAN FOR " in front of queries running through
Calcite and show the results/comparison in an html page like in
phoenix-20150826123638.htm. If it's problematic to have to insert different
strings, just modify the grammar of Phoenix to use "EXPLAIN PLAN FOR" instead
of just "EXPLAIN".

>
> The work to integrate Phoenix with Calcite has come along far enough that
> queries both against the data table and through a secondary index is
> functional. As a checkpoint, we should compare performance of as many queries
> as possible in our regression suite for the calcite branch against the latest
> Phoenix release (4.5.0). The runtime of these two systems should be the same,
> so this will give us an idea of the overhead of query parsing and compilation
> for Calcite. This is super important, as it'll identify outstanding work
> that'll be necessary to do prior to any releases on top of this new stack.
