Parquet Files

What problem does it solves? This Skill streamlines the creation, management, and incremental updating of Parquet files in C#, addressing challenges like memory management, multi-threading, and dynamic schema generation for large datasets. It helps users efficiently store and process big data, saving development time and optimizing resource usage.

Core Features & Use Cases

• Dynamic Schema Generation: Automatically create Parquet schemas from DataTable or dictionary structures, handling type conversions.
• Memory-Efficient Batching: Implement strategies for processing large datasets in batches, clearing memory, and forcing garbage collection to prevent OutOfMemory exceptions.
• Thread-Safe Updates: Utilize ParquetUpdateQueue and SemaphoreSlim for safe, concurrent writing and incremental updates to Parquet files.
• Use Case: Develop a data pipeline that continuously syncs millions of records from a MySQL database to a Parquet file, ensuring incremental updates, deduplication, and efficient memory usage even with multi-threaded data ingestion.
