Transparent chunk transformation (compression) of index directory
-----------------------------------------------------------------
Key: LUCENE-2583
URL: https://issues.apache.org/jira/browse/LUCENE-2583
Project: Lucene - Java
Issue Type: Improvement
Components: Store
Affects Versions: 3.0.2, 3.0.1, 3.0, 2.9.3, 2.9.2, 2.9.1, 2.9, 2.4.1
Reporter: Mitja Lenič
Priority: Minor
In some cases user is willing to sacrifice speed for space efficiency or better
data security. I've developed driver for Directory that enables transparent
compression (any transformation) of directory files, by using decorator
pattern. With current experience, compression ratios are between 1:5 to 1:10,
which depends on type of data stored in index.
Directory files are sliced into fixed chunks, each chunk separately transformed
(eg. compressed, encrypted, ...) and written to supporting (nested) directory
for storage.
I've create project page at [http://code.google.com/p/lucenetransform/] and am
also prepared to join contrib/store.
