storages::mysql::CommandControl Struct Reference

#include </data/code/userver/mysql/include/userver/storages/mysql/options.hpp>

Detailed Description

A structure to control timeouts for MySQL queries

There is a single parameter, execute, which limits the overall time the driver spends executing a query, which includes:

• connecting to MySQL server, if there are no connections available and connection pool still has space for new connections;
• waiting for a connection to become idle if there are no idle connections and connection pool already has reached its max size;
• preparing the statement, if it's absent in statements cache;
• executing the statement;
• fetching all the statement results, if any, and not in cursor mode.

In case of a timeout the client gets an exception and the driver drops the connection (no further reuse will take place), otherwise the connection is returned to the pool.
