Maxwell Guo commented on CASSANDRA-18534:
-----------------------------------------
Hello, as for this ticket ,I am going to make these SSTable format settings
both in cassandra.yam and table level in TableParams (So I think there will be
a new ticket for cassandra's driver~~~ ).
The strength of the validity of the configuration is table level > yaml . if
both yaml and table param is setted. Table level validity is greater，then yaml
's .If none of them is setted, use the default.
Organization of table-level parameters can be a map , like compaction.
Besides, I think we have to modify the cqlsh and add dtest as I have done for
CASSANDRA-15402.
> Make sstable format configurable per table

> Key: CASSANDRA-18534
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18534
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Branimir Lambov
> Assignee: Maxwell Guo
> Priority: Normal
>
> Some SSTable format settings need to be configurable per table for better
> efficiency. This includes:
> - {{row_index_granularity}}
> - {{bloom_filter_fp_chance}}
> - {{crc_check_chance}}
> - {{min/max_index_interval}}
> Some of these are currently configurable using direct properties of tables.
> Having them as format properties makes better sense and should also support
> specifying useable combinations of settings, e.g.
> {code:java}
> CREATE TABLE ... WITH sstable_format = "bti-fast";
> CREATE TABLE ... WITH sstable_format = "bti-small";
> {code}
> where {{bti-fast}} and {{bti-small}} can be defined in {{cassandra.yaml}}
> e.g. as
> {code:java}
> sstable.format.options:
> - bti-fast:
> row_index_granularity: 1kiB
> bloom_filter_fp_chance: 0.01
> - bti-small:
> row_index_granularity: 32kiB
> bloom_filter_fp_chance: 0.1
> {code}
