> I have a question about InnoDB and how it would handle updates on the > order of about 3,000-5,000 a second. The UPDATEs update a single record > on a primary key. In MySQL, it does a table lock thus serializing the > updates. There are a few selects, though on a couple of orders of > magnitude less often. The table locks have the potential to cause > problems at this volume. > > So to avoid the table locks, I have considered using InnoDB. However, it > syncs to disk after every UPDATE and I don't think that will work. why not run with innodb_flush_log_at_trx_commit=2 or 0? > The > disk is a RAID 10 array of 6 15K drives (3x2). > > Any suggestions? > > --steve- Best regards, Heikki Tuuri Innobase Oy http://www.innodb.com Foreign keys, transactions, and row level locking for MySQL InnoDB Hot Backup - a hot backup tool for MySQL -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
