      MongoDB 4.0 will add support for multi-document transactions, making it the only database to combine the speed, flexibility, and power of the document model with ACID data integrity guarantees. Through snapshot isolation, transactions provide a globally consistent view of data, and enforce all-or-nothing execution to maintain data integrity.

      Transactions in MongoDB will feel just like transactions developers are familiar with from relational databases. They will be multi-statement, with similar syntax (e.g. start_transaction and commit_transaction), making them familiar to anyone with prior transaction experience. The changes to MongoDB that enable multi-document transactions will not impact performance for workloads that do not require them. In MongoDB 4.0, which will be released this summer*, transactions will work across a single replica set, and MongoDB 4.2* will support transactions across a sharded deployment......
