Hi, Is your table MyISAM or InnoDB?
Andrew -----Original Message----- From: Morten [mailto:my.li...@mac.com] Sent: 15 June 2009 21:23 To: mysql@lists.mysql.com Subject: The size of an index (INDEX_LENGTH) Hi, I dropped an index on a table with 25M records today. The INDEX_LENGTH in information_schema.tables shrank from 3834642432 to 3215982592, ie. ~618Mb difference The index was on an int(11) column. That means each index key takes up ~618Mb/25M ~= 25 bytes but that doesn't sound right? Is that true, or is information_schema.tables unreliable or?
