Class AsyncCollection

java.lang.Object
com.couchbase.client.java.AsyncCollection

public class AsyncCollection extends Object
The AsyncCollection provides basic asynchronous access to all collection APIs.

This type of API provides asynchronous support through the concurrency mechanisms that ship with Java 8 and later, notably the async CompletableFuture. It is the async mechanism with the lowest overhead (best performance) but also comes with less bells and whistles as the ReactiveCollection for example.

Most of the time we recommend using the ReactiveCollection unless you need the last drop of performance or if you are implementing higher level primitives on top of this one.
