How to preview/read head of a compressed parquet file? #133

Open jucabot opened 2 years ago

jucabot commented 2 years ago

My case is to preview the head (top 100 rows) of a gzip compressed parquet file.

Opening a gz compressed file with ParquetReader.openFile() fails with "not a valid parquet file". Is it possible to handle partial Gzip parquet file with parquetjs?
