Subject Re: Ignite community is building Calcite-based prototype

(Looping in the dev lists as suggested by Julian.)

Julian, Calcite community, let me know what you think about this option.
We're planning to host an Apache Ignite meetup with our group [1]
on November 13th or 14th in the San Francisco Bay Area. The desired topic
is the new Ignite SQL engine based on Calcite. Alex Goncharuk will be
representing the Ignite community doing the presentation.

Is there anybody from the Calcite community (Julian or mister X) who can
join the meetup and do a Calcite-intro talk? Alex will be presenting next.
We would also invite the members of Calcite Bay Area Group. Ignite
community will take care of all org hurdles.
