Subject [jira] [Commented] (AVRO-1414) Compression with C++ DataFile
Date Thu, 19 Dec 2013 18:41:07 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13853128#comment-13853128
] 

Doug Cutting commented on AVRO-1414:
------------------------------------

This looks great.  Tests pass for me and I can read the compressed file written by C++ using
Java's command line tools.  +1  I will commit this soon unless someone objects.

FYI for others, the patch for a GitHub commit can be obtained by adding '.patch' to the url,
e.g.:

https://github.com/salilab/avrocpp/compare/d8afad009069f056168a6b10600fcf91a302b95a...compression.patch

> There is no way to use compression with the C++ DataFileReader and C++ DataFileWriter,
from what I can tell. Adding compression of the written blocks using boost streams is relatively
straight forward and I can provide a patch if people are interested. 
> However, there are a couple caveats:
> - the windows builds of boost don't currently include zlib support (required for compression)
by default. You have to do extra work to get it.
> - I don't know if doing it that way is compatible with other avro implementations
