I updated the agenda on meetup to include Julian's talk around spatial queries.
So far we have four presentations lasting approximately 1h45 so I still find the duration reasonable. Of course if there are more people interested to present something we can schedule another meetup in April as Julian suggested. I am always happy to see what other people are working on and more Calcite use-cases. Best, Stamatis On Sun, Jan 3, 2021 at 2:09 AM Julian Hyde <jhyde.apa...@gmail.com> wrote: > In other news....
