Comment: Nothing of substance has changed since the last time this was declined. There's one paragraph added, which is referenced to three sources which do not mee WP:RS, i.e. a blog post, etc. -- RoySmith (talk) 04:30, 30 January 2019 (UTC)

Apache Arrow is an open source software library for columnar in-memory data structures and processing.[2][3][4]
Arrow is sponsored by the nonprofit Apache Software Foundation[5] and was announced by Cloudera in 2016[6]. Arrow is a component, rather than a standalone piece of software, and as such is included in many popular projects, including Apache Spark and pandas.[7]
It defines a language-independent physical memory layout, enabling zero-copy, zero-deserialization interchange of flat and nested columnar data amongst a variety of systems such as Python, R, Apache Spark, ODBC protocols, and proprietary systems that utilize the open source components.[8][9] Apache Arrow is a complement to on-disk columnar data formats such as Apache Parquet and Apache ORC in that it organizes data for efficient in-memory processing by CPUs and GPUs.
Arrow has been proposed as a format for in-memory analytics,[10] genomics,[11] and computation in the cloud.[12]
Comparisons
Apache Parquet and Apache ORC are popular examples of on-disk columnar data formats. Arrow is designed as a complement to these formats for processing data in-memory.[13]. The hardware resource engineering trade-offs for in-memory processing vary from those associated with on-disk storage.[14] The Arrow and Parquet projects includes libraries that allow for reading and writing data between the two formats.[15]
Daniel Abadi, Darnell-Kanal Professor of Computer Science at the University of Maryland[16] and a pioneer of column-oriented databases,[17] reviewed Apache Arrow in March 2018.[18] "The time is right for database systems architects to agree on and adhere to a main memory data representation standard," he concluded. "[If your] workloads are typically scanning through a few attributes of many entities, I do not see any reason not to embrace the Arrow standard."
