Redis client monad.

Execute the given redis commands stepwise. I.e. every command is send to the server and the response fetched and parsed before the next command. A failing command which produces a RedisError will interrupt the command sequence and the error will be thrown as an exception.

Execute the given redis commands pipelined. I.e. commands are send in batches to the server and the responses are fetched and parsed after a full batch has been sent. A failing command which produces a RedisError will not prevent subsequent commands from being executed by the redis server. However the first error will be thrown as an exception.

Execute the given publish/subscribe commands. The first parameter is the callback function which will be invoked with channel and message once messages arrive.

Connection pool.

Default settings.

• host = localhost
• port = 6379
• idle timeout = 60s
• stripes = 2
• connections per stripe = 25
• max. wait queue = unbounded
• connect timeout = 5s
• send-receive timeout = 10s

Maximum connections per pool stripe.

Maximum length of the wait queue, i.e. the queue where attempts to acquire a connection from the pool build up if all connections are in use. If the maximum length has been reached, attempting to acquire a connection will cause a ConnectionsBusy ConnectionError.

When a pool connection is opened, connect timeout is the maximum time we are willing to wait for the connection attempt to the redis server to succeed.

General error, e.g. parsing redis responses failed.

A single send-receive cycle took too long.
