Type specific compression
-------------------------
Key: CASSANDRA-2398
URL: https://issues.apache.org/jira/browse/CASSANDRA-2398
Project: Cassandra
Issue Type: New Feature
Components: Core
Affects Versions: 0.8
Reporter: Stu Hood
Cassandra has a lot of locations that are ripe for type specific compression. A
short list:
Indexes
* Keys compressed as BytesType, which could default to LZO/LZMA
* Offsets (delta and varint encoding)
* Column names added by 2319
Data
* Keys, columns, timestamps: see
http://wiki.apache.org/cassandra/FileFormatDesignDoc
A basic interface for type specific compression could be as simple as:
{code:java}
public void compress(int version, Iterator<ByteBuffer> from, int count,
DataOutput to) throws IOException
public void decompress(int version, DataInput from, List<ByteBuffer> to) throws
IOException
{code}
