    Hi Vijay - glad to hear from you.

    Yes, I was referring to cardinality.
    As I can see query is doing a range scan on index T1_INDX11 ... 13M rows, too many rows when compared with the 500 rows that are expected to be retrieved.

    You may want to double-check indexing strategy, may be a new index more aligned with the queries predicate would help.
