Editor’s Note: While Apache Arrow and Apache Parquet are separate projects, the Arrow arrow-rs repository hosts the development of the parquet Rust crate, a widely used and high-performance Parquet implementation. Summary Version 57.0.0 of the parquet Rust crate decodes metadata more than three times faster than previous versions thanks to a new custom Apache Thrift parser. The new parser is both faster in all cases and enables further performance improvements not possible with generated pa...| Apache Arrow
Querying Parquet with Millisecond Latency Note: this article was originally published on the InfluxData Blog. We believe that querying data in Apache Parquet files directly can achieve similar or better storage efficiency and query performance than most specialized file formats. While it requires significant engineering effort, the benefits of Parquet's open format and broad ecosystem support make it the obvious choice for a wide class of data systems. In this article we explain several advan...| Apache Arrow

TLDR: The zero-copy integration between DuckDB and Apache Arrow allows for rapid analysis of larger than memory datasets in Python and R using either SQL or relational APIs. This post is a collaboration with and cross-posted on the DuckDB blog. Part of Apache Arrow is an in-memory data format optimized for analytical libraries. Like Pandas and R Dataframes, it uses a columnar data model. But the Arrow project contains more than just the format: The Arrow C++ library, which is accessible in Py...| Apache Arrow

Bryan Cutler is a software engineer at IBM’s Spark Technology Center STC Beginning with Apache Spark version 2.3, Apache Arrow will be a supported dependency and begin to offer increased performance with columnar data transfer. If you are a Spark user that prefers to work in Python and Pandas, this is a cause to be excited over! The initial work is limited to collecting a Spark DataFrame with toPandas(), which I will discuss below, however there are many additional improvements that are cur...| Apache Arrow
Apache Arrow is a technology widely adopted in big data, analytics, and machine learning applications. In this article, we share F5’s experience with Arrow, specifically its application to telemetry, and the challenges we encountered while optimizing the OpenTelemetry protocol to significantly reduce bandwidth costs. The promising results we achieved inspired us to share our insights. This article specifically focuses on transforming relatively complex data structure from various formats in...| Apache Arrow
