How to MySQLDump a Database Without Locking Tables?

How to Run MySQLDump without Locking Tables

When copying a database from a live production environment to a local development environment, it's crucial to avoid locking the production database. This article provides a solution for this challenge.

The traditional command mysqldump locks tables sequentially as it dumps them. To resolve this issue, consider the following options:

• --lock-tables=false Option: This option can potentially prevent table locking, but it might only be applicable to certain table types.
• --single-transaction Option (for InnoDB Databases): For InnoDB tables, the --single-transaction=TRUE option provides a better solution because it does not require table locking. This option ensures that the dump is performed in a single atomic transaction, eliminating the need for table locks.

Therefore, for InnoDB databases, the recommended command is:

mysqldump --single-transaction=TRUE -u username -p DB

By utilizing this option, you can effectively copy a database from a production environment to a local development environment without incurring any table locks.
