[jira] [Created] (CALCITE-2300) Improve messages shown in materialized view-based rewriting algorithm

Jesus Camacho Rodriguez created CALCITE-2300:
------------------------------------------------

             Summary: Improve messages shown in materialized view-based rewriting algorithm
                 Key: CALCITE-2300
                 URL: https://issues.apache.org/jira/browse/CALCITE-2300
             Project: Calcite
          Issue Type: Improvement
    Affects Versions: 1.16.0
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Currently, we do not log or expose any information on why a specific rewriting based on a materialized view was not triggered. Probably we should do that at a very high level of granularity, for instance using the logger TRACE level. This will help 1) debugging possible missing rewriting options, and 2) possibly providing feedback to user if needed.
