Package org.apache.juneau.marshall.parquet

package org.apache.juneau.marshall.parquet

Apache Parquet serialization and parsing support.

Parquet is a columnar binary format for analytics and data pipelines. This package provides ParquetSerializer and ParquetParser for reading and writing Parquet files, and Parquet as a convenience marshaller.

Parquet is collection-oriented: the serializer accepts Collection<T> or T[] at the root; a single bean is wrapped in a one-element list. The parser always returns List<T>.
