* Speed up SQL IN using SCALAR_IN_ARRAY. Main changes: 1) DruidSqlValidator now includes a rewrite of IN to SCALAR_IN_ARRAY, when the size of the IN is above inFunctionThreshold. The default value of inFunctionThreshold is 100. Users can restore the prior behavior by setting it to Integer.MAX_VALUE. 2) SearchOperatorConversion now generates SCALAR_IN_ARRAY when converting to a regular expression, when the size of the SEARCH is above inFunctionExprThreshold. The default value of inFunctionExprThreshold is 2. Users can restore the prior behavior by setting it to Integer.MAX_VALUE. 3) ReverseLookupRule generates SCALAR_IN_ARRAY if the set of reverse-looked-up values is greater than inFunctionThreshold. * Revert test. * Additional coverage. * Update docs/querying/sql-query-context.md Co-authored-by: Benedict Jin <asdf2014@apache.org> * New test. --------- Co-authored-by: Benedict Jin <asdf2014@apache.org> |
