Max number of connections to create.
std::size_t max_size {151};
When a connection is requested, but all connections are in use, new connections will be created and connected up to this size.
Defaults to the maximum number of concurrent connections that MySQL servers
allow by default. If you increase this value, increase the server's max
number of connections, too (by setting the max_connections
global variable).
This value must be > 0
and >= initial_size
.
