I've been working on a secondary indexing module for redis with a subset of SQL WHERE for selection predicates, if anyone's interested. It's not stable yet, but it's coming along nicely. The idea was actually NOT to create an SQL like database, but just proxy ordinary redis commands via secondary index. So you select ids, and perform HGET or HGETALL on them, etc. And the same goes for indexing - you perform something like HMSET and "through" the index, and it performs the operation while indexing the hash automatically. Also, indexes can be used as direct data types with no automation, you just insert ids and tuples of data into them, and you can query them and get ids back. https://github.com/RedisLabsModules/secondary https://github.com/RedisLabsModules/secondary
