How Can I Run mysqldump Without Locking Tables in MySQL?

Run MySQLDump without Table Locking

The Challenge:

It is desirable to copy a live production database into a local development database without imposing locks on the production database. However, executing mysqldump with the usual arguments results in table locks.

Exploring a Solution:

One possible solution involves employing the --lock-tables=false option. However, it's important to note that this option may not be suitable for InnoDB tables.

Optimizing for InnoDB Tables:

For InnoDB tables, a more appropriate option is --single-transaction. This setting enables mysqldump to perform the dump without acquiring table locks.

Command Structure:

To use the --single-transaction option, the following command structure is recommended:

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

By incorporating these adjustments into the mysqldump command line, it is possible to execute a full dump of the production database without locking tables, facilitating seamless copying into the local development database.
