Hello community,

What is the recomended buckets strategy?

Hello.

I have a lot of different types of documents. Documents of one type is much more than others. Should I transfer huge number of the same type documents to the one bucket and all the rest - in another bucket? Or for each type of document make self bucket?

I've run some benchmarking of sets with ReplicateTo.ONE enabled and found very poor performance (about 300 sets/s on two six-core and 20GB ram servers).

After some research it was found that the cause is replication delay (it is about 1 second) - the code in observePoll() in java client...

CAS and xDCR

If xDCR happens for a particular key/value on a particular node will that updated key get a new CAS value that resulted from the xDCR operation?

In summary do keys get new CAS values from both set and xDCR update operations?
