Convert#

If you haven’t already, download the sample data (see Install):

curl -O https://d37ci6vzurychx.cloudfront.net/trip-data/yellow_tripdata_2024-01.parquet

The vx convert command converts a Parquet file to Vortex, applying compression automatically:

vx convert yellow_tripdata_2024-01.parquet

This produces yellow_tripdata_2024-01.vortex in the same directory. By default it uses BtrBlocks compression, chunking on Parquet row-group boundaries.

Compression strategies#

Choose a compression strategy with --strategy:

# Default: BtrBlocks compressor
vx convert yellow_tripdata_2024-01.parquet --strategy btrblocks

# Compact: more aggressive compression
vx convert yellow_tripdata_2024-01.parquet --strategy compact
