Servicestack.redis Data manipulation

Simple string type data write. Poco is serialized as a JSON string in Redis.

Redis is known for its speed, which is not the quickest. Because each time a separate Redis access is performed on the top loop, a query is made and a response is returned.

[req1]     [====waiting=====] [                      RESP1] [                            req2]                                 [====waiting=====]                                                  [RESP2]

A faster notation is to use pipeline mode. Pipeline mode does not wait for the result of the last query, and it sends the next query immediately. Whenever a response returns, it response the corresponding callback processing.

Here is the code implementation:
