Jess Balint commented on CALCITE-1625:
--------------------------------------
It is certainly related. I can push up the patch I have which copies basic
stats from {{DatabaseMetaData.getIndexInfo()}} to the already present
{{Statistic}} structure. The scope of CALCITE-1545 is not clear. We should
clarify the scope of CALCITE-1545 to build a representation of foreign keys (or
maybe generalized dependencies) and retrieve that via
{{DatabaseMetaData.getImportedKeys()}}. Possibly two separate tasks.

> basic JDBC statistics can be retrieved via

> {{JdbcTable}} to provide stats/key info during planning.
