### MySQL table lock errors
|
||||||
|
|
||||||
|
If you encounter table lock errors during a database dump with MySQL/MariaDB,
|
||||||
|
you may need to [use a
|
||||||
|
transaction](https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html#option_mysqldump_single-transaction).
|
||||||
|
You can add any additional flags to the `options:` in your database
|
||||||
|
configuration. Here's an example:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
hooks:
|
||||||
|
mysql_databases:
|
||||||
|
- name: posts
|
||||||
|
options: "--single-transaction --quick"
|
||||||
|
```
|
||||||
