Parquet taking more memory than sequenceFile.

Parquet taking more memory than sequenceFile.

New Contributor

My data file in SequenceFile format occupied 140gb storage. After converting it to Parquet format the storage increased to 150gb. I am curious why this happened and can this happen. Help!

 

The query I used is 

 

Create table table_name (
....
....
....
) stored as parquet tblproperties("parquet.compress"="ZLIB") as select*from original_table;
