In JRedis you have two options if you are using a front-end that
serves a lot of concurrent processes.
For low (concurrent) number of processes (threads), you can use
JRedisService.  This connector maintains a pool of connections to
Redis and cycles through next available connection to serve service
requests.
For very high (concurrent) number of processes (thread count in the
thousands) -- specially if you will be maintaining a constant load on
the connector -- use the Pipeline with sync() semantics.  Pipeline
uses a single connection, but has much higher throughput.
