Question about Snappy compression format.

[Javier Sanchez Beltran]

Hello Iceberg team!

I have been researching Apache Iceberg to see how would work in our 
environment. We are still trying out things. We would like to have Parquet 
format with SNAPPY compression type.

I already try changing these two properties to SNAPPY, but it didn’t work 
(https://iceberg.apache.org/configuration/):


write.avro.compression-codec
Gzip -> SNAPPY
write.parquet.compression-codec
Gzip -> SNAPPY
In this way:


dataset

          .writeStream()

          .format("iceberg")

          .outputMode("append")

          .option("write.parquet.compression-codec", "SNAPPY")

          .option("write.avro.compression-codec", "SNAPPY")

          …start()




Did I do something in a bad way? Or maybe we need to take care of the 
implementation of this SNAPPY compression?

Thank you in advance,
Javier.
