I don't understand the issue with this. I have some tables that come to me as
latin1_swedish_ci i need to do case sensitive joins so i change all the tables involved in both databases to utf8mb4_cs_0900_as_cs now my queries are very slow ! the 'explain' shows that the indexes are being used. What can be the issue? i am using community version on Microsoft desktop.
