the main table have 29M rows (39GB, servers are "small" and old (2008), 16GB ram, 8core dual-cpu xeon, raid 10 hd with 4 sata disks 250gb each, 4 1Gbps network card ) 20+ process updating, deleting, inserting (oltp, 1000+ qps, i think it will not grow with time) 5+ process running olap with big selects/group/order/min/max/sum/count etc (some queries take more than 5 minutes to end, it's not a problem to user, but a problem when use oltp+olap apps at same table)
today using replication to another server or mysqld process at same machine i don't have problem, olap and oltp runs nice with different mysqld process but when i try oltp + olap at same table at same mysqld, locks begin a problem, i was thinking about creating a replication at same server but to different table (replicate table a to table b) 2015-07-03 18:28 GMT-03:00 Stephane VAROQUI <[email protected]>: > Hi, > > How many writes do you have ?
