Apache Arrow Rust vs Eureka: at a glance
What is Apache Arrow Rust?
Apache Arrow Rust 60.0.0 ships Parquet page index APIs and removes an ownership bottleneck in the Flight path
Apache Arrow Rust released version 60.0.0 with two notable changes: new PageIndexBuilder and PageIndexProvider APIs for Parquet page indexes, and a breaking ownership fix to batches_to_flight_data() that eliminates a redundant data copy. The project runs a stable major-release cadence with active maintenance backports for security and correctness fixes.
What is Eureka?
Eureka cut its first release in two years, and the notes live in a release candidate, not the tag.
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.

Apache Arrow Rust 60.0.0 ships Parquet page index APIs and removes an ownership bottleneck in the Flight path
◆ Current state
Apache Arrow Rust released version 60.0.0 with two notable changes: new PageIndexBuilder and PageIndexProvider APIs for Parquet page indexes, and a breaking ownership fix to batches_to_flight_data() that eliminates a redundant data copy. The project runs a stable major-release cadence with active maintenance backports for security and correctness fixes.
◆ Where it's heading
The Parquet work is the consistent throughline — each major release expands codec support, compression capabilities, or predicate pushdown infrastructure. Page index APIs close a gap for Rust-based query engines that already handle bloom filters but lacked native page-level access. The Flight API ergonomics changes reflect ongoing work to remove unnecessary clones from Arrow-native data pipelines.
◆ Prediction
Future releases will continue refining Parquet's ALP floating-point encoding (changes began in 60.0.0) and likely add more granular page-level statistics access. The IPC sans-IO encoder shipped in 59.2.0 is likely to get broader adoption hooks in the next few versions.
Eureka
5.0DEVOPS
Eureka cut its first release in two years, and the notes live in a release candidate, not the tag.
◆ Current state
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.
◆ Where it's heading
This is a maintenance-mode project shipping a catch-up release rather than a roadmap. The substantive content is backports and dependency hygiene — the perf work is explicitly ported from 2.x, and the last two candidates exist only to bump xstream and fix the publish pipeline. The 2.0.x line saw its own small patch, so both lines are alive but neither is being extended.
◆ Prediction
Direction is hard to read from a feed where the release tag carries less information than its candidates. The pattern suggests further releases will be driven by CVE remediation in transitive dependencies rather than by feature work.
