Hello,
I migrated from phpBB to bbPress recently. My forum has ~1Million posts. My postmeta table is 30GB.
Is there anything I can do to shrink it?
I noticed there are many lines for every post like _bbp_old_xxxx, which i suspect comes from migration.
It’s safe to delete all those records with _old_ in it? Or anything else? 30GB seems quite too much even for that amount of posts, compared to the old phpbb db size…

Anyone?

Postmeta size should not be that big.

I have 2.6m+ posts and it is way smaller.

Can you make a query and list, how many distinct meta_keys you have in your DB.
