Couchbase Java SDK 3.2

The Couchbase Java client allows Java applications to access a Couchbase cluster. It offers synchronous APIs as well as reactive and asynchronous equivalents to maximize flexibility and performance.

Scope scope = bucket.scope("inventory");
Collection collection = scope.collection("airport");
MutationResult result = collection.mutateIn(
        "airport_1254",
        Collections.singletonList(MutateInSpec.upsert("foo", "bar")),
        mutateInOptions().durability(DurabilityLevel.MAJORITY)
);
