ParquetCache

ParquetCache()

Cache expressions as Parquet files using a snapshot invalidation strategy.

This storage class saves intermediate results as Parquet files in a specified directory and uses a snapshot-based approach for cache invalidation. The snapshot strategy ensures cached data is only invalidated when the expression’s definition changes, making it suitable for stable datasets.
