David Capwell commented on CASSANDRA-18441:
-------------------------------------------
bq. Regarding a numeric ID - since we bumped the cache version I think we can
add an explicit mapping to the header of the cache file, something like format
name -> id, and use that id, whichever it is. This way the scope of numeric ID
will be limited to the cache only.
so the start of the cache is a map of name -> id, which is scoped to this file
only? Works for me, its what I am used to when working with enums in storage
in other projects.
> Improvements to SSTable format configuration
> --------------------------------------------
>
> Key: CASSANDRA-18441
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18441
> Project: Cassandra
> Issue Type: Improvement
> Components: Local/SSTable
> Reporter: Branimir Lambov
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 5.x
>
>
> 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.
