It seems that you got some problem with the generated code, take this [1] to
debug the code and to see which line caused the compilation error.

Haisheng,
You are confusing logical and physical algebra.
A target DB might have physical operators that can implement several logical
operators. Just because an IN list is represented as an OR it doesn’t mean that
it has to be executed as an OR.
We don’t HAVE TO add every physical operation i

- downloaded the artifacts, checked hash, verified signature, built and ran
tests. All are OK
- use `diff -r` to compare the artifact and the git tag. Like what Julian
has pointed out, I can find a difference about license but it can be
addressed after this vote.

Thanks Julian for explaining the NOT IN to everyone. I am sorry for not making
myself clear.
For that kind of simple 2-valued logic uncorrelated NOT IN subquery, SQL Server
and Greenplum can generate efficient plan with null aware ANTI SEMI join.
Hash ANTI SEMI Join for NOT IN
Join Co
Just in case: Oracle DB has 'null aware' joins. For instance: 'hash join
anti na' which is a single join with two inputs.
I expect that databases can implement 'not in' semantics efficiently (at
least they should be more efficient than enumerable)

I want to remind everyone how hard it is to evaluate NOT IN queries.
Here is an example query:
sqlline> !connect
jdbc:calcite:model=core/build/resources/test/hsqldb-model.json sa sa
> !set outputFormat csv
> EXPLAIN PLAN FOR SELECT * FROM dept WHERE deptno NOT IN (SELECT mgr FROM emp);

I wanted to reply and share our recent requirement for handling SQL like
the following `error_code IN (3002, 3030)' and the challenges we
faced. For our implementation on top of Apache Kudu, each disjunction
creates a `Scanner' – a resource we need to limit as it represents a
denial of service atta
Hello everyone,
Thanks Chunwei for taking care of this release.

Similarly to Enrico, I also found some issues with the deprecated version

hi Danny,
I didn't mention, but I use calcite 1.21.0.
have attempted to use the function already with no success; it didn't seem
to actually change the provider.
have used the RelMetadataQuery.THREAD_PROVIDERS directly and it worked
perfectly.
i assume it is because the function RelOptCluster#se
The Apache Jenkins build system has built Calcite-Master (build #1848)
Status: Failure
Check console output at https://builds.apache.org/job/Calcite-Master/1848/ to
view the results.
The suggested way to set up the RelMetadataProvider is through
RelOptCluster#setMetadataProvider [1]. If you want to customize the
RelMetadataQuery, take the document in RelMetadataQueryBase [2] for a reference.

I only had to fix a deprecation warning, changing from
ReduceExpressionsRule.FILTER_INSTANCE to
CoreRules.FILTER_REDUCE_EXPRESSIONS, see [1] below
