#include </data/code/userver/mysql/include/userver/storages/mysql/component.hpp>
MySQL/MariaDB client component.
Provides access to a MySQL/MariaDB cluster.
The component will lookup connection data in secdist.json via its name.
Connection settings are described as a JSON object mysql_settings
, containing descriptions of MySQL/MariaDB clusters.
Important note: the uMySQL driver does NOT perform an automatic primary detection and always considers the first host in hosts
list an only primary node in the cluster.
Name | Description | Default value |
---|---|---|
initial_pool_size | initial connection pool size (per host) | 5 |
max_pool_size | maximum connection pool size (per host) | 10 |
