For transactional tables similar to InnoDB, –single-transaction is a much better possibility than –lock-tablesbecause it doesn't need to lock the tables in any respect. If you require routines to be created with their unique timestamp attributes, do not use –routines. Instead, dump and reload the contents of the mysql.proc table directly, utilizing a MySQL account that has appropriate privileges for the mysql database. If you require occasions to be created with their authentic timestamp attributes, do not use –events. Instead, dump and reload the contents of the mysql.event table immediately, using a MySQL account that has acceptable privileges for the mysql database. It causes the dump output to include a CHANGE MASTER TO assertion that indicates the binary log coordinates of the dumped reproduction's source. If you liked this article therefore you would like to collect more info with regards to deep copy nested iterable (or improved itertools.tee for iterable of iterables) kindly visit our own site. The CHANGE MASTER TO statement reads the values of Relay_Master_Log_Fileand Exec_Master_Log_Pos from the SHOW SLAVE STATUS output and uses them for MASTER_LOG_FILE and MASTER_LOG_POS respectively. These are the supply server coordinates from which the duplicate ought to start replicating. The mysqldump command is incessantly used to create an empty instance, or an occasion including knowledge, on a replica server in a replication configuration. The following options apply to dumping and restoring data on replication source and duplicate servers. Mysqldump advantages embody the comfort and suppleness of viewing or even editing the output before restoring. You can clone databases for improvement and DBA work, or produce slight variations of an current database for testing. It isn't supposed as a quick or scalable resolution for backing up substantial amounts of information. With large information sizes, even if the backup step takes an affordable time, restoring the data could be very slow because replaying the SQL statements includes disk I/O for insertion, index creation, and so on. Mysqldump output can include ALTER DATABASE statements that change the database collation.
