### Configuring JDBC connection pooling
To configure Apache ActiveMQ Artemis to use a database with a JDBC connection pool
you need to set the data source properties, for example:
```xml
<store>
<database-store>
<data-source-properties>
<data-source-property key="driverClassName" value="com.mysql.jdbc.Driver" />
<data-source-property key="url" value="jdbc:mysql://localhost:3306/artemis" />
<data-source-property key="username" value="artemis" />
<data-source-property key="password" value="artemis" />
<data-source-property key="poolPreparedStatements" value="true" />
</data-source-properties>
<bindings-table-name>BINDINGS</bindings-table-name>
<message-table-name>MESSAGES</message-table-name>
<large-message-table-name>LARGE_MESSAGES</large-message-table-name>
<page-store-table-name>PAGE_STORE</page-store-table-name>
<node-manager-store-table-name>NODE_MANAGER_STORE</node-manager-store-table-name>
</database-store>
</store>
```
You can find the documentation of the data source properties at https://commons.apache.org/proper/commons-dbcp/configuration.html.
To mask the value of a property you can use the same procedure used to [mask passwords](masking-passwords.md).
Please note that the reconnection works only if there is no client sending messages. Instead, if there is an attempt
to write to the journal's tables during the reconnection, then the broker will fail fast and shutdown.
## Zero Persistence
In some situations, zero persistence is sometimes required for a
