Starting with version 1.3, ArangoDB provides support for user-definable transactions.
Transactions in ArangoDB are atomic, consistent, isolated, and durable (ACID).
These ACID properties provide the following guarantees:
- The atomicity principle makes transactions either complete in theirentirety or have no effect at all.
- The consistency principle ensures that no constraints or other invariantswill be violated during or after any transaction.
- The isolation property will hide the modifications of a transaction fromother transactions until the transaction commits.
- Finally, the durability proposition makes sure that operations from transactions that have committed will be made persistent. The amount oftransaction durability is configurable in ArangoDB, as is the durabilityon collection level.
