Re: [DISCUSS] Towards Calcite 1.17.0

I would love to see if we can close out/merge some of the really stale PRs on Github.

Here are a few that I think we should resolve before the release:

[CALCITE-1025] Add support for HTTP Basic auth (for proxies) in Avatica: (JIRA is marked as resolved and this PR is probably irrelevant since Avatica is now in a different repo)

Add support for converting a MongoDB date to a SQL timestamp type: (Could not find relevant JIRA. No tests. Original contributor probably lost context, since it's almost 4 years old)

CALCITE-1681 Provide a way to copy RelNode trees between clusters: (No review, despite the contributor asking for one. Do you think it would be possible to finish this? PR is more than a year old, so contributor might have lost context)

CALCITE-1748: make method getSchema to be overridable: (The proposed solution appeared to be unnecessary according to the comments on JIRA, so this is probably safe to close. Can the JIRA issue be marked as resolved or do we still need to work on it?)

[CALCITE-1866] dateTime FLOOR to HOUR cause MySQL connector throw SQLException: (Original contribution missing a test case. Seems to be abandoned by the contributor. I think it shouldn't be too onerous if someone could carry the PR and add a test).

[CALCITE-1882] Can't obtain the user defined aggregate function such as sum,avg by calcite: (Was dead for a while, but contributor addressed comments 2 months ago. Can someone please review so we can get this in?)

These are just some PRs I found from a quick look through Github. I think a few of them should be easy to carry so that we can get them into the release. For PRs #180 and #422 can someone confirm if they are safe to close? If so, I'll ask INFRA to close them.

There are also a bunch of PRs from a year ago that are going stale. If possible we should review, carry,  close or merge them. Having a lot of stale PRs without any activity or review may deter contributors new to the community from contributing.

I'll add CALCITE-2331 as at least a nice-to-have. I believe Andrei is
working on a PR and this would be a good bug to have fixed.

predicate (A or B) and C is failing for some adapters

To answer Michael's question: I don't think we should delay the
report, nor should we hurry the release. It's fair to say that 1.17 is
in its final stages. There was a lot of activity on avatica-1.12 from
a lot of individuals, and the community is in great shape.

Here are the cases listed by Volodymyr, converted into links:

* CVSS - ?
* Performance issue
in getPulledUpPredicates - Zoltan
* Upgrade Avatica -
* EXTRACT - Julian

* Arrays in MongoDB
- Volodymyr
* Java8 syntax - Kevin
* Babel - Julian
(blocked by 2259)
* JDBC adapter
timestamps - Julian to review

Hi Michael,

There are several Jiras, which I think are blockers for the
release: CALCITE-2379, CALCITE-2384 and CALCITE-2365 + CALCITE-2303.
Also, there is a list of the Jiras, which would be good to include to
1.17: CALCITE-194, CALCITE-2259, CALCITE-2280, CALCITE-2339.

So I think we need at least couple of weeks to resolve these issues and
release 1.17.

Also, please let me know if there are other issues-blockers for the
release, or if some of these issues may be omitted.

Kind regards,
Volodymyr Vysotskyi

It also would be great to have at least a BETA version of Babel parser

Just wanted to check in with how we're doing with progress towards a
release. It's not a rush at all, but I'm preparing the board report
July and wondering if I should wait to include the 1.17.0 release. It
sounds like there are a few other things that still need to be wrapped
so I'm fine if we don't release for another couple weeks.

Thanks again Volodymyr for taking this on!

Calcite 1.16.0 was released on March 19 (more than two months ago).
We have solved over 48 issues[1] since then, therefore we should
discussing about releasing Calcite 1.17.0.

I have created [2] to track the release.

We will start a release process after the Avatica 1.12 is released.

I went through the list of opened PRs during the last month, and
the list of Jiras which possibly be merged before the release:

CALCITE-2303: Support DECADE time unit in EXTRACT function - changes
done, depends on the Avatica release
CALCITE-2329: Enhance SubQueryRemoveRule to rewrite IN operator with
constant from the left side more optimally - I will make required
at the beginning of next week

* CALCITE-2321: Support ragged fixed length value union be variable
In review (Julian)*

* CALCITE-2291: Add rule to push Project past Correlate - I will
this next week*

List of other pull requests which require review or additional
CALCITE-2327: In 3 valued logic mode (b and not b) may not be
CALCITE-2302 / CALCITE-2325: Implicit type cast support - Julian
comment into the Jira
CALCITE-2331: evaluation of predicate (A or B) and C is failing for
adapters - created PR only with a test for this Jira
CALCITE-2209: Support loading JSON model file through URL - Shuyi
added a comment into the Jira
CALCITE-2324: Extract seconds, minutes from date works not correct
CALCITE-2319: Druid Expressions - Output Type of Boolean expressions
be set to FLOAT.
CALCITE-500: Ensure EnumerableJoin hashes the smallest input - PR is
CALCITE-2301: Remove the 10-second-timeout restriction in
ResultSetEnumerable - needs additional rework.

Please let me know, if there are any Jiras should be included into


Kind regards,
Volodymyr Vysotskyi
