Hello Marquez, Thank you for the report. I can not repeat described behavior with dummy data on 5.6.16/5.5.36. Please could you provide the complete repeatable test case(exact table DDL, and all data, and the select query that you are using - please make it private when you upload). Thanks, Umesh

Hi, To be honest with you I cannot longer reproduce this issue. We are still experiencing this problem, but removing the subpartition part does not make a difference. It is really weird because everything was fine until we migrated from MySQL 5.5 to 5.6. We are now testing new indexes in order to overcome this performance issue. Indexes are been reworked, which is really strange as they used to work perfectly in MySQL 5.5
