Although requested, there is currently no Redis storage handler available for AWL or TxRep, but MySQL storage tuned with the MEMORY engine, or InnoDB engine with a sufficiently big innodb_buffer_pool parameter, or together with the MySQL memcache plugin, would offer similar performance as Redis, while allowing much better vertical and horizontal scalability (it would work better for both bigger tables and multiple concurrent accesses as well).
