[DISCUSS] Apache Calcite Meetup March 2023
Hi all,
Last meetup [1] was roughly 12 months ago. How about organising another one
around mid March 2023?
As previous years, I was thinking of a virtual event (via zoom) with a few
presentations followed by open discussion.
I was also considering the possibility of a hybrid event (in person
somewhere in bay area and virtual via zoom) but there are various
constraints for March. If things work out well we can talk about the hybrid
event later on and aim for June/July assuming there is enough interest.
Are there people willing to give a talk around Calcite?
What do people think in terms of timing?
Best,
Stamatis

Re: [DISCUSS] Apache Calcite Meetup March 2023
Posted by Stamatis Zampetakis <za...@gmail.com>.
I would like to thank everyone who attended, supported, and helped
organize this meetup with of-course a special mention for our
presenters Julian, Mihai, and Alessandro!
I had a great time yesterday evening and learned many new things along
the way. From some personal feedback I got, I know that there were
many people who really appreciated the presentations and the open
discussion.
If there is more feedback about improvements, changes, or things that
you would like to see in a next meetup don't hesitate to share here or
privately.
I will post the videos online on youtube once I finish some small
post-processing.
Then I will update the talks section in the website [1] with links to
the slides, videos, and other relevant information.
Best,
Stamatis

Re: [DISCUSS] Apache Calcite Meetup March 2023
Posted by Stamatis Zampetakis <za...@gmail.com>.
Hi all,
The link for the zoom meeting is now available in the event details on
meetup [1] and will share it also in this thread a few hours before the
event starts.
The event starts on March 15, 2023 18:00 UTC [2].
Note that there is a bug in meetup.com and some pages display a wrong time
for the event (problems observed for people in CET); if in doubt use [2] as
the source of truth.
Best,
Stamatis

Re: [DISCUSS] Apache Calcite Meetup March 2023
Posted by Stamatis Zampetakis <za...@gmail.com>.
Thanks Mihai for proposing to give a talk! Looking forward to it.
I just created and announced the event on meetup [1]. The agenda may change
but hopefully the date/time will remain the same.
Apriori we will use a regular Zoom meeting to host the event (like last
time) but if people have other preferences let me know. I will share the
respective link here and in the meetup platform as we approach the date.
Best,
Stamatis

That would be very interesting. (I see Frank McSherry among your co-authors and everything Frank does is very interesting.)

RE: [DISCUSS] Apache Calcite Meetup March 2023
Posted by Mihai Budiu <mb...@vmware.com.INVALID>.
Hello,
I would like to propose the following presentation for a meetup.
Thank you,
Mihai Budiu
-----------------
Building a streaming incremental view maintenance engine with Calcite
Speaker: Mihai Budiu - VMware Research
Duration: 20-40 minutes
The DBSP open-source project
(https://github.com/vmware/database-stream-processor) is a Rust
runtime that unifies seamlessly streaming queries and incremental view
maintenance (IVM). The SQL to DBSP compiler is an open-source
(https://github.com/vmware/sql-to-dbsp-compiler) SQL compiler, based
on Calcite, that targets the DBSP runtime. The compiler has passed
more than 7 million SQL tests from SQLLogicTest (with 3 tests
failing). We will present the core design of the IVM engine and the
way we use Calcite to compile SQL to streaming computations. We
discuss a few syntactic and sematic differences between SQL dialects
that we have identified. Should Calcite support a notion of an "input
SQL dialect", that would allow it to emulate behaviors that differ
between other established SQL engines?

Hello everyone,
the proposed date and time is fine with me and I'd be happy to hear
Julian's talk.
In addition, together with Stamatis, we could present how the extended
logging capabilities introduced via CALCITE-4704
<https://issues.apache.org/jira/browse/CALCITE-4704> and CALCITE-4991
<https://issues.apache.org/jira/browse/CALCITE-4991> in Calcite planner
could be used to debug planning issues, showcasing this in the context of
Apache Hive.
The title, abstract and estimated duration will follow soon if the topic
can be of interest for the community.
Best regards,
Alessandro

Re: [DISCUSS] Apache Calcite Meetup March 2023
Posted by Stamatis Zampetakis <za...@gmail.com>.
Hello,
Thanks for reviving the thread Gavin.
I would be very interested to hear the talk by Julian at the meetup
especially since I will not be able to attend the long version in Austin.
Recapping all changes of the past year might be a bit difficult to be done
by one person. However, if someone wants to
present/explain/highlight/debate certain contributions in more detail
that would be certainly helpful.
For those who are able to give a talk at the meetup I would kindly ask to
send the title, duration, and short abstract of their proposed talk so that
I can prepare a tentative agenda and put it online.
To fix up the date what do you think about March 15, 2023 at 18:00 (UTC)?
It's hard to find a slot that is perfect for everyone so I will consider
first the preferences/constraints of people that will present.
Best,
Stamatis

Just to follow up on this, maybe the Calcite org could schedule something
for March and advertise it?
The email may have gotten buried in folks' inboxes
I'm sure there are people who would be interested in hearing about the
developments and usecases in Calcite-land
Maybe someone could give a recap of features/enhancements in the past year
as well?
Would be really a bummer not to have a meetup this year!

I'd be up for a meetup.
I am giving a talk "Cubing and metrics in SQL, oh my!" at Data Council
in Austin on Mar 29, so I could give a shorter talk on the same topic
at the meetup, if people are interested.

Hey Stamatis,
I would love to attend virtually, and I have a topic I would like to
