Redis on Heroku Sharding

Question

I'm evaluating possibility of using heroku plus RedisToGo addon.

I've read that there is a possibility to set up standalone redis cluster with sharding and replication.

However in heroku documentation I see examples of JedisPool usage instead of ShardedJedisPool.

Does it mean that redis on heroku does not scale and shard? Or is it done internally?

Answer 1

Unfortunately, the Redis To Go Add-on does not support sharding or replication in any of its plans.

However, it's often the case that add-on providers will work with you to support custom requirements if you contact them directly. You can expect the cost of such plans to increase appropriately.
