Taming Floating-Point Statistics in Apache Parquet: IEEE 754 Total Order and NaN Counts

Fri, 29 May 2026 00:00:00 +0000

Column statistics are the secret to Apache Parquet’s blazing fast performance. By storing compact summaries—like min, max, and null counts—for row groups, column chunks, and pages, readers can easily skip irrelevant data that doesn’t match a query.

However, floating-point values throw a wrench into this simple model. The IEEE 754 standard defines special values like NaN (Not a Number), signed zeros (-0.0 and +0.0), and infinities. Their comparison rules don’t play well with the simple “total order” (a strict smaller-to-larger ranking) expected by most data-pruning algorithms. To fix this, the Parquet community recently clarified the standard by combining IEEE 754 total order semantics with an explicit nan_count field in the statistics.

Variant Type in Apache Parquet for Semi-Structured Data

Fri, 27 Feb 2026 00:00:00 +0000

The Apache Parquet community is excited to announce the addition of the Variant type—a feature that brings native support for semi-structured data to Parquet, significantly improving efficiency compared to less efficient formats such as JSON. This marks a significant addition to Parquet, demonstrating how the format continues to evolve to meet modern data engineering needs.

While Apache Parquet has long been the standard for structured data where each value has a fixed and known type, handling heterogeneous, nested data often required a compromise: either store it as a costly-to-parse JSON string or flatten it into a rigid schema. The introduction of the Variant logical type provides a native, high-performance solution for semi-structured data that is already seeing rapid uptake across the ecosystem.

Native Geospatial Types in Apache Parquet

Fri, 13 Feb 2026 00:00:00 +0000

Geospatial data has become a core input for modern analytics across logistics, climate science, urban planning, mobility, and location intelligence. Yet for a long time, spatial data lived outside the mainstream analytics ecosystem. In primarily non-spatial data engineering workflows, spatial data was common but required workarounds to handle efficiently at scale. Formats such as Shapefile, GeoJSON, or proprietary spatial databases worked well for visualization and GIS workflows, but they did not integrate cleanly with large scale analytical engines.
