--------------------------------
Summary: Add more tests for ARRAY functions(Spark Library)
Key: CALCITE-6042
URL: https://issues.apache.org/jira/browse/CALCITE-6042
Project: Calcite
Issue Type: Improvement
Reporter: Ran Tao
Assignee: Ran Tao
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 array function of spark itself, which
is actually important. Because the function itself is a function of spark, and
the array of spark has some differences in behavior from the array of calcite.
# 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 cases like:
{code:java}
array_except(array(2), array(2, 3)) {code}
