I wouldn't worry about it. I have a table here with nearly a billion rows, and it fetches based on the primary key in "0.00 sec". > my calculation was mostly based on resources - like ram. like i mentioned > earlier the .MYD and .MYI files together on the current one that i have - > which has about 1.2 million records - are 90 mgb. > are the .MYI files kept in ram or both .MYD and .MYI? Neither of them are kept in RAM. You want a reasonable amount of memory for buffers, query cacheing, etc, but you don't need to hold any of the files in memory. My main concern with large tables is disk space, especially if you're ever going to want to do ALTER TABLE, when you will need enough free space to hold the existing and new copies of the table on disk at the same time. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
