Marian Dvorsky updated BEAM-3874:
---------------------------------
Description:
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.
