Using RedisIO for hashes and selecting a database

I am new to Beam and I am familiarizing myself with various aspects of this
cool framework.  I need to be able to get key/value pairs from a Redis
hash, and not just the key/value store in the default database (database
0).  I have only seen the ability to get key/value pairs that have been set
in Redis, but the source code does not make it seem like I can look up
keys/values in a hash, and I have not seen a way to select a database
number.  Have I missed something, or is this feature not (yet)
implemented?  If I want to use this, am I going to have to extend the
RedisIO class?  Thanks in advance!

Hi,

RedisIO currently doesn't support option to select a database.

Can you please create a Jira I will do the improvement ?

Thanks,
Regards
JB
