Apache Arrow has reached version 4.0.0 of the language-agnostic development platform for in-memory data analytics. This release covers 3 months of development work and includes 711 resolved issues.
Amid the changes Java applications can now enable zero-copy optimisations when writing data in Arrow Flight, while Arrow Flight itself was packaged for C#/.NET. A CSV writer has been added, which can infer timestamp columns with fractional seconds.
Arrow Datasets received various performance improvements and new features: new columns can be projected from arbitrary expressions at scan time, and read performance has been improved for Parquet on high-latency filesystems.
For full details of the changes, see the Apache Arrow blog and the Apache Arrow 4.0.0 changelog.

Qt Creator 4.15 adds usability enhancements
Qt Creator 4.15 is out, with a number of updates to the editing, project creating and debugging capabilities of the cross-platform integrated development environment.
This release fixed several issues that caused difficulties in successfully parsing CMake projects with special prerequisites. Qt 6-based CMake projects can also target iOS.

Splunk gives it to you all in one
Machine data analytics firm Splunk has launched the Splunk Observability Cloud, an enterprise-grade analytics-powered observability platform aimed at IT and DevOps teams.
The new release is comprised of a suite of solutions for infrastructure monitoring, application performance management, digital experience monitoring, synthetic monitoring, log investigation and incident response.
Splunk said IT and DevOps teams can get answers about what’s happening in their infrastructure via Observability Cloud’s unified interface with metrics, traces and logs, all of which data is collected in real-time, without sampling and at any scale.
