Detailed description of the Python Process Communication naming pipeline, detailed description of the python process Pipeline
A pipe is a simple FIFO communication channel, which is unidirectional communication. Generally, a process is started to create an MPS queue. Then, this process creates one or more sub-processes to accept MPs queue information. Because the MPs queue is one-way communication, you ofte
Typically, after a request is made by the Redis client, it usually blocks and waits for the Redis server to process, and after the Redis server finishes processing the request, the result is returned to the client via a response message. This is a bit similar to HBase's scan, which is usually the client side that gets each record as a RPC call server. In Redis, is there something like hbase Scanner caching, a request that returns multiple records? Yes, this is pipline. Official introduction http

There is this serious idea in everyone's heart .
The manual learns that pipeline only sends out multiple REDIS instructions, and Redis does not guarantee that these specified executions are atomic; Multi is equivalent to a REDIS transaction, guaranteeing the atomicity of the entire operation, Avoid inconsistencies in the resulting data due to midway errors. The test is that the pipeline is more than 10 times times more efficient than the other way, enabli

Custom SQL statements
When the API provided does not meet our requirements for SQL statements, we usually write our own SQL statements, CI also provides a more powerful, to meet our needs of the general SQL API.
