Subject [jira] [Commented] (FLINK-5944) Flink should support reading Snappy Files
Date Mon, 11 Sep 2017 17:10:01 GMT

Chesnay Schepler commented on FLINK-5944:
-----------------------------------------

Option 2/3 are out imo as they extend the existing API which is already really loaded.
Option 4 is not really viable, since realistically, users are just not gonna do it.

So i would go for Option 1.

> Snappy is an extremely performant compression format that's widely used offering fast
decompression/compression. 
> This can be easily implemented by creating a SnappyInflaterInputStreamFactory and updating
the initDefaultInflateInputStreamFactories in FileInputFormat.
> Flink already includes the Snappy dependency in the project. 
> There is a minor gotcha in this. If we wish to use this with Hadoop, then we must provide
two separate implementations since Hadoop uses a different version of the snappy format than
Snappy Java (which is the xerial/snappy included in Flink).
