Batcher can be used to collect things to be handled in batches after a given period of time or number of operations.

It was created to collect multiple writes to a Redis server and do batch writes using the pipelined operation for an application which gets a massive amount of writes. This reduces the number of connections needed by writing each operation immediately by collecting them over a period of time and writing them all using fewer Redis connections.

If available in Hex, the package can be installed as:

1. Add batcher to your list of dependencies in mix.exs:

   def deps do [{:batcher, "~> 0.0.1", github: "behe/batcher"}] end

2. Configure and start batcher:

   worker(Batcher, [[timeout: 1000, limit: 100, action: &SomeModule.some_action/1], []])

The configured action will receive the batched list of things sent to it until the timeout or limit has triggered the action.

To add items to the batcher call Batcher.append(myitem)
