Description

CEP-17 and CASSANDRA-17056 abstracted some interfaces for SSTable format implementations and defined a method of plugging in specific configurations.

This method is brittle and asks users to specify format identifiers whose configuration does not provide value but can be the source of conflicts and problems. On the other hand it makes important choices non-obvious, as the selection of format to write is given by the order of configured interfaces.

An improved specification mechanism needs to be put in place before Cassandra 5 is released.
