Vladimir Sitnikov created CALCITE-3677:
------------------------------------------

             Summary: Add assertion to EnumerableTableScan constructor to validate if the table is suitable for enumerable scan
                 Key: CALCITE-3677
                 URL: https://issues.apache.org/jira/browse/CALCITE-3677
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.21.0
            Reporter: Vladimir Sitnikov
            Assignee: Vladimir Sitnikov


RelOptTableImpl#toRel (and some test methods) use EnumerableTableScan.create explicitly even in case the table is not implementable with enumerable scan.

It does not hurt much for sql to rel translation, however, it is sad when a plan fails during execution.

So EnumerableTableScan should have an assertion to prevent invalid uses.
