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
