How Can I Perform a Non-Blocking Database Dump of My Production Data?

Non-Blocking Database Dumping for Production Data

Copying live production data into a local development environment can be crucial for testing and troubleshooting. However, a traditional approach using mysqldump can lock tables, hindering ongoing production operations.

Initial Attempt and Encountered Issue

Initially, the attempt was made using the command:

mysqldump -u root --password=xxx -h xxx my_db1 | mysql -u root --password=xxx -h localhost my_db1

Unfortunately, this method resulted in table locks throughout the dumping process.

Addressing the Locking Problem

To resolve the locking issue, a few options were explored:

  • --lock-tables=false Option: Innodb tables do not support this option, making it unsuitable for this scenario.
  • --single-transaction Option: For Innodb databases, this option can effectively prevent table locking:
mysqldump --single-transaction=TRUE -u username -p DB

This command executes the dump in a single transaction without requiring table locks.
