> AvroIO currently uses CodecFactory.deflateCodec(6) as the default codec for writes.
> That compresses well, but is quite expensive.
> Snappy codec offers sparser, but much faster compression, and is typically a better CPU/storage
tradeoff except for very long lived files. 
> We should consider switching the default to Snappy.
