Subject Re: Ignite community is building Calcite-based prototype

Denis,

I’ve been a follower and admirer of Ignite for several years, so I am delighted that you
are considering Calcite.

Ask questions on the dev list, log JIRA cases if you find them, and we’ll do our best to
help.

I’d like to bring to your attention RelBuilder. Some people want to go from SQL text to
executable plan, but others want to drop in at the relational algebra level, and RelBuilder
is a convenient interface for the latter.

(The other) Julian
