-----------------------------------------
Summary: semi-immutable CQL rows
Key: CASSANDRA-7297
URL: https://issues.apache.org/jira/browse/CASSANDRA-7297
Project: Cassandra
Issue Type: Improvement
Components: API, Core
Reporter: Tupshin Harper
There are many use cases, where data is immutable at the domain model level.
Most time-series/audit trail/logging applications fit this approach.
A relatively simple way to implement a bare-bones version of this would be to
have a table-level schema option for "first writer wins", so that in the event
of any conflict, the more recent version would be thrown on the floor.
Obviously, this is not failure proof in the face of inconsistent timestamps,
but that is a problem to be addressed outside of Cassandra.
Optional additional features could include logging any non-identical cells
discarded due to collision.
