Package com.couchbase.client.java

Class Collection

java.lang.Object

com.couchbase.client.java.Collection

public class Collection
extends Object

The Collection provides blocking, synchronous access to all collection APIs.

If asynchronous access is needed, we recommend looking at the ReactiveCollection and if the last drop of performance is needed the AsyncCollection. This blocking API itself is just a small layer on top of the AsyncCollection which blocks the current thread until the request completes with a response.

Since:

3.0.0
