Parquet Format

The uncompressed Parquet format is also supported but it not enabled by default since a crafted input with hostile intention can easily crash the server. Also, it may not be fully supported see this comment. However, it can be enabled by setting the environment variable MINIO_API_SELECT_PARQUET=on.

For development with docker-compose or docker-compose-gateway*, enable it like this via .env file:

MINIO_API_SELECT_PARQUET=on

For development with helm, you can enable the Parquet format via .value.yaml file like this:

minio:
  # ...
  enableParquetFormat: true

For MinIO client (mc), mc sql subcommand can be used. You need to create alias with --api s3v4 like this:

./mc alias set minio http://localhost:8080 12345678 12345678 --api s3v4
