Scaling Redis - use Twemproxy or wait 1 month for Redis Cluster?

[John Lee]

Hi,

We're using redis in production, but we need to scale it in about 1-2 months. Is it worth waiting a month for Redis Cluster, or I should start implementing it with Twemproxy? What are the advantages/disadvantages over one or the other? 

Thanks

If you use Twemproxy, what you get is automatic sharding, without
automatic rebalancing and fault tolerance.

So my suggestion is that that your team should evaluate Redis Cluster
as it is in the current beta for automatic sharding of data + fault
tolerance, and avoid for now to use what Twemproxy would not allow
anyway, like online add/removal of nodes or live resharding of data.
You can use those advanced features later maybe, as the project gets
more stable.

So if you find that for your uses Redis Cluster is working well during
the next weeks, you may start directly with it.
Otherwise if you find the project to be still to immature for your
users, you may go for Twemproxy and upgrade to Redis Cluster later.

Cheers,
Salvatore

twemproxy and redis cluster have different features.

so, you should check two of them first. 

for example.

twemproxy can't support some commands of redis.

(multi/exec, pub/sub etc)

Thanks. I was afraid that Cluster in Beta might be too unstable for production, but if the basic features are said to work well we can give it a try.
