Ran Tao updated CALCITE-6042:
-----------------------------
Summary: Add tests for ARRAY functions(Spark Library) (was: Add tests with
spark array function for ARRAY functions(Spark Library))
> Add tests for ARRAY functions(Spark Library)
> --------------------------------------------
>
> Key: CALCITE-6042
> URL: https://issues.apache.org/jira/browse/CALCITE-6042
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.35.0
> Reporter: Ran Tao
> Assignee: Ran Tao
> Priority: Major
>
> Currently, we support a serials of Spark ARRAY functions such as
> ARRAY/ARRAY_DISTINCT/ARRAY_EXCEPT/ARRAY_POSITION/ARRAY_CONTAINS...
> however, the test cases of these functions use calcite array constructor such
> as
> {code:java}
> array_except(array[2], array[2, 3]) {code}
> We don't have any testcase related to the Spark's array function, however
> this is actually important. Because these array functions belong to Spark
> library, and the Spark's array has some different behaviors with calcite's
> array constructor.
> # use map(k, v, ...) rather than map[k, v, ...]
> # allows empty map such as map(); however calcite map constructor not
> support it.
> we expect to add some test cases like:
> {code:java}
> array_except(array(2), array(2, 3))
> array_except(array(2), array()) {code}
