HTTP Interface for Transactions
ArangoDB’s transactions are executed on the server. Transactions can be executed by clients in two different ways:
The difference between these two is not difficult to understand, a short primer is listed below. For a more detailed description of how transactions work in ArangoDB and what guarantees ArangoDB can deliver please refer to Transactions.
Stream Transactions allow you to perform a multi-document transaction with individual begin and commit / abort commands. This is similar to the way traditional RDBMS do it with BEGIN, COMMIT and ROLLBACK operations.
This the recommended API for larger transactions. However the client is responsible for making sure that the transaction is committed or aborted when it is no longer needed, to avoid taking up resources.
At the end of the function, the transaction is automatically committed, and all changes done by the transaction will be persisted. No interaction is required by the client beyond the initial start request.
