This is a simple wrapper script that starts a command once redis has finished loading its dataset in memory.
Installation:
$ pip install waitredis
Sample usage:
$ sudo restart redis-server && waitredis redis-cli time redis-server start/running, process 20573 1) "1379426556" 2) "512325"
Without the wrapper script (and if redis takes a significant amount of time to load its dataset from disk), you get an error:
$ sudo restart redis-server && redis-cli time redis-server start/running, process 20504 (error) LOADING Redis is loading the dataset in memory
