XF 1.1 MYSQLI Conversion issues..


Active member
I just converted over to MySQLI and now can not post on the site. Any help would be greatly appreciated.

I am getting:

What version of MySQL are you running? Also, what is the storage engine for the xf_search_index table? MyISAM or InnoDB?

If you go to your performance options (Admin -> Options -> Performance), disable the "Enable Delayed Insert SQL Queries" option.

Not all MySQL servers/storage engines support it. All my tables are ndbcluster (instead of InnoDB) and it doesn't support delayed either.

I think I misread the question...

I use ndbcluster because it's fault tolerant (any db server can fail or be taken down completely for things like hardware upgrades and it doesn't affect site).

It scales linearly (my setup can handle around 15,000,000 SQL SELECTs per second *while* doing around 5,000,000 INSERT/UPDATE/DELETEs per second).

It also does a lot of nice things natively as a bonus (hot/non-blocking backups), you can upgrade MySQL even across major versions without a millisecond of downtime.

This is a pretty good overview:

Sexy... :) In the middle of upgrading the cluster to mysql-5.6.15 ndb-7.3.4, and users don't even know. :)
