[jira] [Updated] (CALCITE-6989) Enhance RexBuilder#makeIn to create SEARCH for ARRAY literals

     [ https://issues.apache.org/jira/browse/CALCITE-6989?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stamatis Zampetakis updated CALCITE-6989:
-----------------------------------------
    Description: 
Currently [RexBuilder#makeIn|https://github.com/apache/calcite/blob/e9db5bdb7c78cdbbed5bb7917b62a53b6450aa40/core/src/main/java/org/apache/calcite/rex/RexBuilder.java#L1787] method creates an OR expression when the input ranges are ARRAY literals. Ideally, we should handle ARRAY literals in the same way that we handle ROW literals and create a SEARCH expression that is a more powerful abstraction.

+Example+
{noformat}
RexBuilder#makeIn($0, ARRAY [100, 200], ARRAY [300, 400]) 
{noformat}

+Before+
{noformat}
OR(=($0, ARRAY(100, 200)), =($0, ARRAY(300, 400)))
{noformat}

+After+
{noformat}
SEARCH($0, Sarg[[100:INTEGER, 200:INTEGER]:INTEGER NOT NULL ARRAY, [300:INTEGER, 400:INTEGER]:INTEGER NOT NULL ARRAY]:INTEGER NOT NULL ARRAY)
{noformat}

Subsequently we can take advantage of the SEARCH operator for more powerful simplifications (RexSimplify) and/or generating IN clauses when we go from RelNode back to SQL (RelToSqlConverter).
