Jun Rao commented on KAFKA-1493: -------------------------------- James, Thanks for the patch. A couple of more questions. 1. The following header frame used in the patch doesn't seem to match exactly what's described in http://fastcompression.blogspot.com/2013/04/lz4-streaming-format-final.html. So, we are inventing our own header? Is that ok? /* * Message format: * HEADER which consists of: * 1) magic byte sequence (8 bytes) * 2) compression method token (1 byte) * 3) compressed length (4 bytes) * 4) original message length (4 bytes) * and compressed message itself * Block size: 64 Kb * */ 2. If the io stream code in this patch is identical to that in lz4-java, could we just use lz4-java instead? Thanks, > Use a well-documented LZ4 compression format and remove redundant LZ4HC option > ------------------------------------------------------------------------------ > > Key: KAFKA-1493 > URL: https://issues.apache.org/jira/browse/KAFKA-1493 > Project: Kafka > Issue Type: Improvement > Affects Versions: 0.8.2 > Reporter: James Oliver > Assignee: Ivan Lyutov > Priority: Blocker > Fix For: 0.8.2 > > Attachments: KAFKA-1493.patch, KAFKA-1493.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
