Apache Arrow 1.0.0 now available

The Apache Arrow team has announced the release of Apache Arrow 1.0.0. Apache Arrow is a development platform for in-memory analytics. 

Version 1.0.0 is the 18th release of the platform. It features 810 resolved issues from 100 contributors. 

According to the team, this release marks a transition to binary stability of the columnar format and a transition to Semantic Versioning for the Arrow software libraries. 

The columnar format has received a number of changes in this release: 

  • The metadata version was bumped to a new version.
  • Dictionary indices gained the ability to be insight integers.
  • A new “Feature” enum was added.
  • Optional buffer compression using LZ4 or ZStandard was added to the IPC format.
  • Decimal types gained an optional “bitWidth” field that defaults to 123. According to the team, this will allow them to support other decimal widths in the future, such as 32- and 64-bit.
  • The validity bitmap buffer was removed.

In addition, the team has expanded integration testing to test for extension types and nested dictionaries. 

Apache Arrow Flight, which is a framework for high-performance data services, also received a few updates. It now offers DoExchange, which is a bidirectional data endpoint, as well as DuGet and DuPut. In addition, servers and clients can now set read and write options in all languages. This will make compatibility with earlier versions of Apache Flight easier, the team explained. 

The team also updated support for C++, Java, Python, R, Ruby and C GLib, and Rust. More information is available here.

2022: The year of hybrid work

Remote work was once considered a luxury to many, but in 2020, it became a necessity for a large portion of the workforce, as the scary and unknown COVID-19 virus sickened and even took the lives of so many people around the world.  Some workers were able to thrive in a remote setting, while others felt isolated and struggled to keep up a balance between their work and home lives. Last year saw the availability of life-saving vaccines, so companies were able to start having the conversation about what to do next. Should they keep everyone remote? Should they go back to working in the office full time? Or should they do something in between? Enter hybrid work, which offers a mix of the two. A Fall 2021 study conducted by Google revealed that over 75% of survey respondents expect hybrid work to become a standard practice within their organization within the next three years.  Thus, two years after the world abruptly shifted to widespread adoption of remote work, we are dec...
