Can I use this for Delta Lake operations?

Yes, it includes patterns for Delta Lake integration, covering data versioning, time travel, compaction, and vacuuming operations.

How does this skill improve query performance?

It implements predicate pushdown, row group filtering, and efficient partitioning, which allows applications to read only the specific data needed instead of the entire file.

What is the Parquet-Coder skill?

It is a specialized capability for Claude Code that provides expert patterns and code implementations for managing Apache Parquet files efficiently using Python.

Which Python libraries are featured in this skill?

The skill focuses on implementations using Pandas, PyArrow, and the deltalake library for robust data manipulation.

Does it support data schema changes?

Yes, the skill includes specific utilities for schema unification and evolution, enabling you to merge datasets with different but compatible column structures.
