The remainder of the properties for the connection are optional, but you can set the connection
numbers (initial connections, minimum connections, maximum connections, and the idle timeout) by
setting the pool parameters:
pool.setInitConn( 5 );
pool.setMinConn( 5 );
pool.setMaxConn( 250 );
pool.setMaxIdle( 1000 * 60 * 60 * 6
Once the parameters have been configured, initialize the connection pool:
pool.initialize();
The pool, and the connection to your
To set the hashing algorithm used to select the server used when storing a given key, use
pool.setHashingAlg():
pool.setHashingAlg( SockIOPool.NEW_COMPAT_HASH );
Valid values are NEW_COMPAT_HASH,
hashing algorithms. For a consistent hashing algorithm, use CONSISTENT_HASH. These constants are
equivalent to the corresponding hash settings within libmemcached.

When using the TCP protocol, you can use a simple text based interface for the exchange of
information.
When communicating with memcached, you can connect to the server using the port configured for the
server. You can open a connection with the server without requiring authorization or login. As soon as
you have connected, you can start to send commands to the server. When you have finished, you can
terminate the connection without sending any specific disconnection command. Clients are encouraged
to keep their connections open to decrease latency and improve performance.
Data is sent to the
