What problem does it solve?

Proactively analyzes Parquet file operations and suggests optimization improvements for compression, encoding, row group sizing, and statistics. Activates when reading or writing Parquet files or discussing Parquet performance.

Core Features & Use Cases

  • Compression and encoding: Recommend modern codecs like ZSTD with appropriate levels; dictionary encoding where beneficial.
  • Row group sizing & statistics: Set max row group size and enable statistics to improve pruning.
  • Column projection & streaming: Use projections and streaming for large datasets to minimize memory usage.
  • Batching & streaming: Prefer streaming over collect for large results.

Quick Start

Tune a Parquet writer's properties for a sample dataset and verify improved read performance with a projection.
