[ANNOUNCE] Apache Calcite 1.24.0 released

The Apache Calcite team is pleased to announce the release of Apache
Calcite 1.24.0.

Calcite is a dynamic data management framework. Its cost-based
optimizer converts queries, represented in relational algebra, into
executable plans. Calcite supports many front-end languages and
back-end data engines, and includes an SQL parser and, as a
sub-project, the Avatica JDBC driver.

This release comes two months after 1.23.0. It includes more than
80 resolved issues, comprising of a few new features as well as
general improvements and bug-fixes. It includes top-down rule
apply and upper bound space pruning, Presto dialect and many
more bug fixes and improvements.

You can start using it in Maven by simply updating your dependency to:

  <dependency>
    <groupId>org.apache.calcite</groupId>
    <artifactId>calcite-core</artifactId>
    <version>1.24.0</version>
  </dependency>

Thanks for your kindly reminder, Julian.

P.S. I will add this note to the document.

I will send it again. Sorry about that.

Chunwei,

Did you send an email to announce@apache.org? I haven't seen anything on that list yet.

I'll send a tweet on @ApacheCalcite shortly.

Julian, I would like to review 4134 and 4080. But I think it's much better
if you can open merge requests for those issues.

Thanks! Chunwei! Good job.

The link address of the Presto dialect implementation in
https://calcite.apache.org/news/2020/07/24/release-1.24.0/ seems to be
wrong.

Re: [ANNOUNCE] Apache Calcite 1.24.0 released

Thanks for being release manager, Chunwei! Great job.

I assume that master is open for commits? I have quite a few stacked up: 3923, 4079, 4134, 4128, 4080, 2569, 2160.

I’d like Ruben to review 3923/4079 (class loader deadlock), Rui & Michael to review 2569/2160 (rework table functions, and spatial table functions) and would like volunteers to review 4134 (interval expressions), 4080 (character literals as column aliases), 4128 (refactor CSV/file adapters).
