Roadmap event: call for speakers

[Gian Merlino <gi...@apache.org>]

Hi Druids,

We are looking to put on a virtual event called "Druid.NEXT" in June
highlighting things that people in the community are working on. This is a
call for speakers for that event!

Date is TBD, but likely late June. The event will be on the shorter side,
about meetup-length (an hour or two). If you are interested in giving a
5–10 minute talk about something you plan to contribute this year, then let
us know!

1) If the thing you're working on isn't yet on the "community roadmap"
GitHub issue at https://github.com/apache/druid/issues/14157, post there so
we can add it.

2) Reply to this email, or post on that GitHub issue, with a note that
you're interested in speaking.

Looking forward to what's next,

Gian
