----------------------------------------
Summary: Allow custom constant map in RelOptPredicateList
Key: CALCITE-4978
URL: https://issues.apache.org/jira/browse/CALCITE-4978
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.29.0
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
{{RelOptPredicateList}} tries to infer constants from the predicates passed to
the {{of(...)}} factory methods. However, the underlying mechanic is limited
and handles only a small subset of possible constant derivation strategies. We
may want to implement such strategies gradually (inference from AND/OR, ranges,
etc.), but it might be a big effort.
This ticket proposes a new factory method that allows users to pass custom
constant maps.
