Hi Peter

Thanks for your suggestions.

Actually, we have only 4.5 GB database size so we have added the buffer pool size is 5GB. We hope this is enough for the buffer.

We have enabled the profiling only for gathering the queries stats after that we disabled.

We have already created indexes dynamically from the application end on Temp table and have added indexes at DB level by which we got some improvement than earlier.

Please find the below indexes from DB side


mysql> SELECT TABLE_SCHEMA,TABLE_NAME,COLUMN_NAME,INDEX_NAME FROM INFORMATION_SCHEMA.STATISTICS WHERE TABLE_SCHEMA = 'cst_db' and TABLE_NAME='BCT_PROD';
+--------------+------------+---------------+-------------------+
| TABLE_SCHEMA | TABLE_NAME | COLUMN_NAME | INDEX_NAME |
+--------------+------------+---------------+-------------------+
| cst_db | BCT_PROD | PRODREV_ID | PRIMARY |
| cst_db | BCT_PROD | ProductNo_Rst | PROD_idx |
| cst_db | BCT_PROD | BCT_PRODREV | BCT_PRODREV_idx |
| cst_db | BCT_PROD | PRODNO | PRODNO_RSTATE_idx |
| cst_db | BCT_PROD | RSTATE | PRODNO_RSTATE_idx |
| cst_db | BCT_PROD | DESCRIPTION | DESCRIPTION_index |
| cst_db | BCT_PROD | RSTATE | RSTATE_index |
| cst_db | BCT_PROD | PRODNO | idx4 |
