Episode notes
Apache Parquet Advantages
- Apache Parquet's key advantage is its combination of essential columnar format features and a vast ecosystem.
- It excels in compression and read speed due to columnar storage, projection pushdown, and predicate pushdown.
Apache Arrow Benefits
- Arrow is a language-agnostic in-memory columnar format minimizing data interchange costs and enabling fast computation.
- It offers a standard way to represent data, avoiding reimplementation of type systems and mappings.
Columnar Format and SIMD
- Columnar in-memory formats like Arrow enable SIMD instructions for fast computation.
- Arrow's computation kernels further enhance performance by providing optimized operations.
