Szehon Ho commented on HIVE-11912:
----------------------------------
Hey [~Ferd] I guess table properties can still be used to configure compression
type, this change would not change that.
I actually think something like parquet.compression should be in
SerdeProperties, as its a special property unique to the serde. For example
avro's serdeProperties include the location of the schema.url, which is unique
to Avro.
I've actually been confused for awhile why you can configure serde properties
as table properties (so they seem interchange-able). But in any case, the
MetaStoreUtils.getSchema appends all the Serde properties to the Table
properties, such that its passed in to the code you pointed out
(ParquetHiveSerde.initialize())
> Make snappy compression default for parquet tables

> Snappy is a popular compression codec for Parquet, and is the default in many
> Parquet applications, increasing the performance.
> This change would make it the default for new Hive Parquet tables.
