Re: maximum number of records in a table

to have about 8 gigs of ram to successfully use a table like that. either that or cluster 2 machines with 4 gigs each and split the table. does this sound reasonable? is my logic flawed somehow? i'll appreciate any comments on this subject thanks... On 6/11/07, kalin mintchev [EMAIL

Re: maximum number of records in a table

You should be fine. 100 000 000 is not that much. Just make sure you set the right keys (and then query by them) on the table and even more importantly, set caches and buffers to utilize your RAM appropriately. thanks. Olaf On 6/12/07 11:09 AM, kalin mintchev [EMAIL PROTECTED

Re: mysql limits

Search speeds and CPU with MyISAM is quite good. I tried InnoDb and insert speeds was far too slow because of its row locking versus MyISAM's table locking. Some people have been able to fine tune InnoDb but it requires even more RAM because InnoDb works best when the entire table fits into

Re: mysql limits

Put as much memory in the machine as possible. Building indexes for a table of that size will consume a lot of memory and if you don't have enough memory, building the index will be done on the hard disk where it is 100x slower. I've had 100M row tables without too much problem. However when

group by problem

Re: group by problem

Basically you can't do what you want either without temporary tables or using a subselect. Subselects are only available in mysql 4.1+ (I think - check the docs) so that may or may not be an option. thanks... pardon my ignorance - how would i do that using subselects? -- MySQL General

but that will get you all records for that category not just the most recently updated. that's the main problem, isn't it? what i'm looking for is the last record for EACH of the categories in the table. i'm aware of the aformentioned options. my problem with group by is that ignores the
