David Capwell commented on CASSANDRA-18441:
-------------------------------------------
bq. but I'd put the selected write format on a parent level
Another option is
{code}
sstable:
format:
default|selected|w/e: big
options:
big:
max_version: nc
# or
sstable.format.default: big
sstable.format.options.big.max_version: nc
{code}
I am ok with your proposal though
{code}
sstable.selected_format=big
{code}
bq. In summary, selected format is not a property of any format, IMO it better
fits to sstable level.
Sounds fine to me
> 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.
