Aerospike Database 8.0 Release Notes
January 22, 2025
Aerospike Database software version 8.0 is now available.
New in this version
This version implements the transactions feature.
New features
- Transactions: A transaction is several commands isolated from commands outside the transaction and executed atomically. Aerospike transactions guarantee one of two outcomes: either all commands succeed together, or one or more commands fail. In case of failure, all records roll back to the state prior to the attempted transaction. No commands outside the transaction can see the state changes being created inside the transaction. This allows you to enforce strict serializability requirements by putting all requests with such requirements into their own transactions.
note
- There are special considerations for downgrade if transactions were attempted. If you need to downgrade, see Downgrade from Database 8.0 before proceeding.
- 'mrt' in the names of new configuration and metrics items indicates that those items are associated with the new transactions feature.
