Membase memory usage
We are using Membase 220.127.116.11 and have been running into some issues in terms of memory scalability. Our use case consists of ~20-30 byte keys with only counter values (incr, decr mutations only). We currently have 20 million keys per 16GB membase server. These counters are used in random order and do not exceed the max value of an integer.
The servers are fine until they start swapping and going to disk because they've hit their limits. 20 million keys for 16GB of ram seems a bit inefficient. Is the use case given not amenable to membase? Or is there some settings that should be tweaked/dealt with in order to optimize for a key heavy dataset.
