Subject [jira] [Resolved] (LUCENE-4584) Compare the LZ4 implementation in Lucene against the original impl
Date Mon, 03 Dec 2012 01:23:58 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adrien Grand resolved LUCENE-4584.
----------------------------------

    Resolution: Won't Fix

Comparing the compressed output against the original impl seemed to be a good mean to detect
bugs, but if we want to be able to have a different algorithm as Uwe suggests, I'll try to
add softer tests (like checking that the algorithm manages to detect a match which is 65535
bytes backwards, gives a reasonable compression ratio on inputs that are known to be easily
compressible, etc.)

> We should add tests to make sure that the LZ4 impl in Lucene compresses data the exact
same way as the original impl.
