Re: speed up the data retriving
I need to see the EXPLAIN for the actual SELECTs you are using, not "SELECT *".
KEY `idx_tagid` (`TagId`), -- redundant, DROP it
KEY `idx_tagidtime` (`TagId`,`TimeStamp`),
DROP one of these:
KEY `idx_time` (`TimeStamp`),
KEY `idxtime` (`TimeStamp`)
You showed this twice: SHOW VARIABLES LIKE '%buffer%';
Why are the values different??
