Gabriel Reid commented on CRUNCH-173:
-------------------------------------
[~stepinto] If you can add it here, it would be super-interesting to hear more
about your test case pipeline (i.e. the size of the tuples that you're writing,
etc). That kind of a speedup sounds awesome!
> Make WritableTypeFamily more compact for composite types

> I'm throwing this out as something of a strawman JIRA: it's always bugged me
> how verbose the serialization of TupleWritable et al. are compared to the
> Avro formats, so I took a crack at changing their underlying serialization to
> be more compact by doing more things in terms of BytesWritable and using the
> wrapping MapFns in order to do more of the de-serialization work. Patch is
> attached, if anyone is interested in this or has an opinion on whether or not
> this is a good idea, I'd love to hear it. The big pro is that Crunch jobs
> that have to use writables will run faster as a result, the downside is that
> it's not backwards compatible and it makes the code more complex.
