[Maria-discuss] Odd behavior with query and connection pool
by Stu Smith 14 Jun '16

14 Jun '16

Hello, Forgive me for reporting this on the behalf of some other developers, I will gather more details as needed. But the basic problem we're having is with a query that: - is always fast the first time ( < 3 seconds ) - is very slow the following time, when using a connection pool (~ 30 seconds) - is pretty fast the following time, when not using a connection pool (5 or 6 seconds) This is even on a single DB with no other load. It's a fairly complicated query with sub queries, grouping, and such. I've been told it creates two temp tables. I know this is not a whole lot to go one - but are there any pointer for connection pool vs no connection pool on a lightly loaded DB? This was actually tried and reproduced with multiple connection pools - hikari-db, c3p0, and apache connection pool. Take care, -stu

[Maria-discuss] R: Odd behavior with query and connection pool
by Federico Razzoli 14 Jun '16

14 Jun '16

Weird issue. I'm trying to figure out how the connection pool can add an overhead to a single query. The only case I can think is if you use a network storage engine (Federated, Connect, Spider) pointing to tables on localhost. Is this the case? More likely... are you sure this problem is caused by the connection pool? * After the first execution, do a SHOW STATUS. Then FLUSH STATUS. Then execute again and, if it takes long time, do another SHOW STATUS. Post your results here, so we can see what happened. * While the query takes a long time, try a SHOW PROCESSLIST from another client. See if the connection is waiting for a lock.

[Maria-discuss] Problems with running out of connections in cluster
by Lee Bennett 13 Jun '16

13 Jun '16

Hi We are running a 7 node cluster (6 data nodes and 1 arbiter node) which span 2 data centers using version 10.1.13. We have had several occasions where the application have gone off and created so many connections that the max connections are filled up which leads to the database becoming unresponsive. The connections cannot be killed and and in the ‘killed’ state forever. Today when this occurred all six cluster node maxed out on connections. The only way to get the servers back is by restarting the databases but when the first node we restarted it tried to connect to the cluster is to IST it could not connected. After shutdown a second node the cluster seemed to sort its self out and everything came back. Is anyone aware of any bugs that might cause this issue. Regards LB
