Timothy Potter created SOLR-15579:
-------------------------------------
Summary: SQL WHERE filter with 20 or more values in the IN clause
results in no filtering on that field
Key: SOLR-15579
URL: https://issues.apache.org/jira/browse/SOLR-15579
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Parallel SQL
Reporter: Timothy Potter
Assignee: Timothy Potter
Calcite has a default threshold of 20 for the number of values in an {{IN}}
clause. If this threshold is reached, then Calcite transforms the IN clause
into an inline table + sub-query which is not handled by {{SolrFilter}}, so
that filter clause gets dropped from the resulting query to Solr, see:
https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/sql2rel/SqlToRelConverter.java#L1143
The easiest solution is to update the
{{config.withInSubQueryThreshold(Integer.MAX_VALUE)}}
I think we should also explore how to work with the sub-query against the
inline table if possible.
