> 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.
