limitations of memcached buckets in 2.1
I'm looking at using couchbase memcached bucket as a replacement for redis. My main motivation is horizontal scaling. The reason I want to use memcached is to get better response times, and have the data fully in memory.
I found the documentation below, which is relevant to 1.8, but I couldn't find any similar document for 2.1 or for future versions.
My main concerns are the fact that replication, rebalancing and persistence are not supported. Are these all true for current versions as well? Any other thing I should consider?
You can find information about Couchbase 2.1 Bucket Types here:
As you can see you have the same limitations regarding memcached buckets.
Based on your requirement, you should just use the "Couchbase Bucket" like that you will have replication, failover,... and no impact on performance, if you have the correct sizing. All the disk I/O operations are done asynchronously this is why you won't see any performance impact.
