Aleksey Yeschenko commented on CASSANDRA-8384:
----------------------------------------------
Overall mostly looks good, with some issues and nits.
Nits:
- CHANGES.txt entries should be short. Ideally a single line, no longer than 80
characters or so.
- this particular message belongs to NEWS.txt, Upgrading section
Issues:
- {{CompressionParameters.asThriftOptions()}} should remain unchanged (use the
old keys. not include {{enabled}})
- {{CompressionParameters.create()}} should not reject {{enabled}} set to
{{true}} and a presence of {{class}} - it should be allowed, there is no
conflict there
- however, if {{enabled}} is set to {{false}}, we should reject any other
options being set. And do the same for {{compaction}} (in a separate ticket)
- even when disabled, we should still store the map with {{'enabled': 'false'}}
in the schema table
> Change CREATE TABLE syntax for compression options
> --------------------------------------------------

> Key: CASSANDRA-8384
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8384
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Aleksey Yeschenko
> Assignee: Benjamin Lerer
> Labels: doc-impacting, docs
> Fix For: 3.x
>
>
> Currently, `compression` table options are inconsistent with the likes of it
> (table `compaction`, keyspace `replication`).
> I suggest we change it for 3.0, like we did change `caching` syntax for 2.1
> (while continuing to accept the old syntax for a release).
> I recommend the following changes:
> 1. rename `sstable_compression` to `class`, to make it consistent
> `compression` and `replication`
> 2. rename `chunk_length_kb` to `chunk_length_in_kb`, to match
> `memtable_flush_period_in_ms`, or, alternatively, to just `chunk_length`,
> with `memtable_flush_period_in_ms` renamed to `memtable_flush_period` -
> consistent with every other CQL option everywhere else
> 3. add a boolean `enabled` option, to match `compaction`. Currently, the
> official way to disable comression is an ugly, ugly hack (see CASSANDRA-8288)
