[jira] [Resolved] (CALCITE-1625) add basic JDBC statistics

     [ https://issues.apache.org/jira/browse/CALCITE-1625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Julian Hyde resolved CALCITE-1625.
----------------------------------
    Resolution: Duplicate

This is a duplicate of CALCITE-1545. Maybe that case needs to be clarified, but we're talking about getting foreign key information from the JDBC adapter to the optimizer, which is the same as this case.

> basic JDBC statistics can be retrieved via {{DatabaseMetaData.getIndexInfo()}}. This can be used in the underlying {{JdbcTable}} to provide stats/key info during planning.
