Review comment:
Just fyi, start is inclusive here but end is exclusive 🤷♂️ not a very
consistent api...

> Support for Redis 5.0 streams (XADD/XREAD/XRANGE) in RedisIO
> ------------------------------------------------------------
>
> Key: BEAM-13159
> URL: https://issues.apache.org/jira/browse/BEAM-13159
> Project: Beam
> Issue Type: New Feature
> Components: io-java-redis
> Reporter: N. M.
> Assignee: N. M.
> Priority: P2
> Time Spent: 11h
> Remaining Estimate: 0h
>
> Redis 5.0 and later support an append-only log data structure called a
> "stream" -- each element has a unique incrementing ID and contains one or
> more string:string key-value pairs.
> This seems like a gimme for a stream processing platform to support, and in
> fact Jedis already has support for XADD/XREAD/XRANGE in it, but the current
> redisIO Read and Write classes only support pcollections of single KVs and
> thus will need some additional work to support streams.
