             Summary: 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
    Affects Versions: 2.33.0
            Reporter: N. M.


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.
