Hi, Have you considered using Xtrabackup to create a replication slave? This is essentially a binary copy kept in sync with the innodb transaction log, and it works great. On Wed, Jan 17, 2018 at 12:55 PM, Conor Murphy < conor_mark_murphy@hotmail.com> wrote:
Hi Marko,
I don't think that's an option
- It would interfere with the normal operations on the master, currently we use a "FLUSH TABLES WITH READ LOCK" with an LVM snapshot to get a consistent copy of the database while the system is up and running. Changing the PARTITIONs to TABLEs would mean having to stop the running system.
- I haven't checked this in a while (> a year), but the last time we looked at swapping a TABLE back to a PARTITION, it took hours, I think it's because it validates that the rows in the TABLE belong in the PARTITION according to the partitioning scheme. MySQL has the "WITHOUT VALIDATION" option to overcome this
