Couchbase Transactions — Java

ACID multi-document transactions. All operations commit atomically or roll back entirely.

Version requirement: Distributed transactions require Couchbase Server 7.0+. The 6.6 developer preview is not recommended for production.

Bank Transfer Example

import com.couchbase.client.java.transactions.error.TransactionFailed;

cluster.transactions().run((ctx) -> {
    TransactionGetResult sender   = ctx.get(collection, "acct_alice");
    TransactionGetResult receiver = ctx.get(collection, "acct_bob");

    JsonObject senderDoc   = sender.contentAsObject();
    JsonObject receiverDoc = receiver.contentAsObject();
