----------------------------------------
Fix Version/s: 5.0
(was: 5.x)
> Make sstable format configurable per table
> ------------------------------------------

> Key: CASSANDRA-18534
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18534
> Project: Cassandra
> Issue Type: Improvement
> Components: Cluster/Schema, Local/SSTable
> Reporter: Branimir Lambov
> Assignee: Maxwell Guo
> Priority: Normal
> Fix For: 5.0

> Time Spent: 0.5h
> Remaining Estimate: 0h

> 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}
