re: mysqlimport blocks all access to database
Yes I am appending to the end of an existing database. So why are rows 1 to N locked if I'm only adding rows at N+1? Wouldn't the write privileges apply to rows being modified? And during this period even an interactive mysql shell hangs until the mysqlimport completes. i.e. I the database is pretty much inaccessible until mysqlimport completes. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, March 28, 2005 12:30 AM To: [EMAIL PROTECTED] Subject: Re: mysqlimport blocks all access to database Hi Joseph, I have been trying to use mysqlimport to load a primarily read only database with data at regular intervals. My problem occurs when my tables are myisam. In this case all access to the database and the tables blocks until mysqlimport completes. The -lock-tables=false parameter does not help. Is this the normal operation? If not how can I still have concurrent read access to the database while mysqlimport is running? Correct me if I am wrong, but the write request has privilege. So ANY read request is queued until the write request finishes. Otherwise you would get inconsistent read results. Am I correct assuming that you are appending the imported data to the existing data in the database ?
