------------------------------------
Summary: ArrayIndexOutOfBoundsException during SqlToRelConverter for
group-by on `case` having `in` expression predicates exceeding
SqlRelConverter.Config InSubQueryThreshold (was:
ArrayIndexOutOfBoundsException during SqlToRelConverter for group-by with `in`
expression predicates exceeding SqlRelConverter.Config InSubQueryThreshold)

> Key: CALCITE-5209
> URL: https://issues.apache.org/jira/browse/CALCITE-5209
> Project: Calcite
> Issue Type: Bug
> Reporter: Ian Bertolacci
> Priority: Major
>
> For these examples assume that:
> - {{`SqlToRelConverter.Config.config().withInSubQueryThreshold(5)`}} has been
> set.
> - The source table has 4 columns (Column_0 through Column_3)
> - Each column is of type BIGINT NOT NULL
> The failing query is:
> {code}
> select
> case
> when Column_3 in (1, 2, 3, 4, 5) THEN 1
> else 0
> end
> from T1000
> group by
> case
> when Column_3 in (1, 2, 3, 4, 5) THEN 1
> else 0
> end
> {code}
> The exception is:
> {code}
> 3
> java.lang.ArrayIndexOutOfBoundsException: 3
