Database optimalisation #30

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

Currently the whole project is great. Can you please post the most optimal 
indexes when having +300.000 headlines in the database. Now the updating 
takes for ages (deleting of old posts takes very long ±10 seconds)

Please help

Wow, and I thought I had a lot of feeds!  I'll see what I can do.

Hi,
I changed most of the primary key columns to unsigned int which are of smaller
size than te default column sizes an result in smaller indices.
I changed some indexes to prefixed ones especially in the fof_item table
because some of them got unecessary large.
I changed the default table type to InnoDB as well, which results in less
disk reads because data and indexes can be kept in memory.
Drop me a mail if you're interested in the schema.
