Subject [jira] Commented: (AVRO-135) add compression to data files
Date Mon, 05 Oct 2009 22:49:31 GMT

    [ https://issues.apache.org/jira/browse/AVRO-135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762437#action_12762437

Henry Robinson commented on AVRO-135:

It's pretty easy to call C from Python - there's a very full featured C API since the standard
Python runtime is C based. (see http://docs.python.org/c-api/). The API takes care of connecting
Python calls to their C equivalents. Then you call into the API to unmarshal the arguments
into C variables and then you can pass them onto the LZF library.

The tricky part is getting reference counting right but if this is a thin layer between Python
and a C LZF library then it probably doesn't need to worry too much about Python object lifetimes.
(Concurrency is also a pain, but again probably not a big issue here).
