13.3. The Memcached Interface Connector
The following enables a Memcached server using the
memcached
socket binding, and exposes the memcachedCache
cache declared in the local
container, using defaults for all other settings.
<memcached-connector socket-binding="memcached" cache-container="local"/>
Due to the limitations in the Memcached protocol, only one cache can be exposed by a connector. To expose more than one cache, declare additional memcached-connectors on different socket-bindings. See Section 13.3.1, “Configure Memcached Connectors”.
13.3.1. Configure Memcached Connectors
The following procedure describes the attributes used to configure the memcached connector within the
connectors
element in Red Hat JBoss Data Grid's Remote Client-Server Mode.
Procedure 13.1. Configuring the Memcached Connector in Remote Client-Server Mode
The
memcached-connector
element defines the configuration elements for use with memcached.
<subsystem xmlns="urn:infinispan:server:endpoint:8.0"> <memcached-connector socket-binding="memcached" cache-container="local" worker-threads="${VALUE}" idle-timeout="{VALUE}" tcp-nodelay="{TRUE/FALSE}" send-buffer-size="{VALUE}" receive-buffer-size="${VALUE}" /> </subsystem>
- The
socket-binding
parameter specifies the socket binding port used by the memcached connector. This is a mandatory parameter. - The
cache-container
parameter names the cache container used by the memcached connector. This is a mandatory parameter. - The
worker-threads
parameter specifies the number of worker threads available for the memcached connector. The default value for this parameter is 160. This is an optional parameter. - The
idle-timeout
parameter specifies the time (in milliseconds) the connector can remain idle before the connection times out. The default value for this parameter is-1
, which means that no timeout period is set. This is an optional parameter. - The
tcp-nodelay
parameter specifies whether TCP packets will be delayed and sent out in batches. Valid values for this parameter aretrue
andfalse
. The default value for this parameter istrue
. This is an optional parameter. - The
send-buffer-size
parameter indicates the size of the send buffer for the memcached connector. The default value for this parameter is the size of the TCP stack buffer. This is an optional parameter. - The
receive-buffer-size
parameter indicates the size of the receive buffer for the memcached connector. The default value for this parameter is the size of the TCP stack buffer. This is an optional parameter.
