View Full Version : Little help: Rebuild Post Cache

27 Jun 2008, 07:00

The board that I admin has nearly 5 million posts.

I suspect that I need to AdminCP->Maintenance->Update Counters->Rebuild Post Cache.

Should I disable the board before doing this?

Is this a processor intensive operation? (will it put a heavy load on the server?).

Thanks for any info or insight.

Yes this is processor intensive.

But why do you need to do this?

Yes this is processor intensive.

But why do you need to do this?Actually, I am not sure that it is needed.

I problem is with a modification that displays an icon based on there being info contained in a field:

<if condition="($post['fieldname'] == '')">
<else />

I was not working (due to a bug!). After I fixed the bug, the ICON does not change in older posts. (the newest ones work as expected). So I suspected that the older posts were being drawn from the cache.

If you give it time it should automatically update the cache. If it doesnt then run that.

Thanks! I thought that might be the case.

I will just wait for it to update itself. (I would rather not force it!)

Just clear out the postparsed table:

TRUNCATE postparsed;

Cache will be rebuild while posts are viewed for the first time.
