What problem are we solving?
When using Redis store there are a lot of single commands sent to Redis sequentially. This causes many round trips and network IO wait.
For example for directories this produces a GET command for each child in the directory. Imagine a folder with a million files, it would sequentially execute 1 million GET commands.
How are we solving the problem?
Using the client-side pipelining feature to send all commands and get all their results in a single roundtrip.
This is implemented for
redis2
stores. If you like the idea I can go ahead and change the other redis stores as well.How is the PR tested?
