> Read operation in RedisIO is for prefix based look ups. While this can be
> used for exact key matches as well, the number of operations limits the
> through put of the function.
> I suggest exposing current readAll operation as readbyprefix and using more
> simpler operations for readAll functionality.
> ex:
> {code:java}
> String output = jedis.get(element);
> if (output != null) {
> processContext.output(KV.of(element, output));
> }
> {code}
> instead of:
