dating 2016 arab contact online - Mysql slave state invalidating

I'm running a 4 servers master-master cluster of My Sql. Replication topology: 1 - 1 UPDATE It seems that server 3 has its SBM at 0, while the other servers are jumping up and down. It looks like the server is busy doing something, and there is a huge delay between when the server gets the statement, and when it executes it. After disabling cache, server 4 is ok but 1&2 are still having this issue. id=60696 If anyone knows how to fix it, i would be glad to hear There is one flaw with mysql's seconds_behind_master value: it only takes into account the position relative to one upstream hop away.

mysql slave state invalidating-89

We lately mved to My SQL V5.5 on Cent OS release 6.7 with master and 2 slaves.

Since then the replication process lags a lot behind the master with the line in the process list of: invalidating query cache entries (table).

You should contact the help centre via the link at the bottom of the page, to ask for your multiple accounts to be merged.

row *************************** Id: 7929352 User: system user Host: db: NULL Command: Connect Time: 69899 State: invalidating query cache entries (table) Info: NULL replication shows Seconds_Behind_Master: 70429 Once the invalidating query cache entries (table) process has finished the slave catches up.

Also, check INNODB STATUS for thread with this status reported. I've now set this to mixed to see if this stops the problem as a workaround.

I'm discounting #38551 as this happened more than once since after turning the query cache off.

, mostly INSERT statements, around 5-10 rows per second. In 5-10 seconds when it will be time to process new data again the same lock up will happen. Query #2 is the updating of the post-processed data.

A PHP based application is running on the server that reads the freshly replicated data every 5-10 seconds, processes it and stores (INSERT ON DUPLICATE KEY UPDATE) results in a separate database . A web application displays the post-processed data for the user. Query #3 is streaming (unbuffered) the newly replicated data for processing.

Unfortunately the thread finally ended so I can't checkout whether #59899 is related or not.

Update: Using an external slave with an RDS master is now possible as well as RDS as a slave with an external master Connecting external My SQL slaves to AWS RDS mysql instances is one of the most wanted features, for example to have migration strategies into and out of RDS or to support strange replication chains for legacy apps.

the global Were the size and type set to 0 when the server was started, or later?
