[jira] [Updated] (LUCENE-4733) Make CompressingTermVectorsFormat
the new default term vectors format?
[ https://issues.apache.org/jira/browse/LUCENE-4733?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adrien Grand updated LUCENE-4733:
---------------------------------
Attachment: LUCENE-4733-javadocs.patch
New patch that adds Lucene42TermVectorsFormat with file format javadocs.
I have set chunkSize=4KB as it seemed to be a good compromise between compression and speed in LUCENE-4599 (this chunk size only accounts for terms and payloads). Moreover, it uses LZ4 compression (which is very light) so that compression/decompression is not the bottleneck even for small indexes which fit into memory.

> In LUCENE-4599, I wrote an alternate term vectors format which has a more compact format, and I think it could replace the current Lucene40TermVectorsFormat for the next (4.2) release?
