Block Nested Loop (1 reply)

hi

we are using mysql 5.7.11 INNODB version and when i am running the query(explain plan), it is giving the warning as Using index; Using join buffer (Block Nested Loop)


Is this causes performance of my query.

I am not able to run my query and taking hours to complete it even though we have indexes on joined columns.

Please let me know, Block Nested Loop is causing the issue.

Thank you
