    final RelOptTableImpl newOptTableImpl = RelOptTableImpl.create(t.getRelOptSchema(), t.getRowType(), newTable);
    // return an EnumerableTableScan with fileSelection being part of digest of TableScan node.
    return DirPrunedEnumerableTableScan.create(oldScan.getCluster(), newOptTableImpl, newFileSelection.toString());
