Apache Arrow Rust vs NATS: at a glance
What is Apache Arrow Rust?
Arrow Rust 60.1.0 ships, redacting Parquet encryption keys and adding read-ahead planning.
Arrow Rust published 60.1.0 on Oct 28, the first minor on the 60 line. It redacts Parquet encryption keys from Debug output and adds a scan_plan for read-ahead in the Parquet push decoder, a separate page-index decoder, per-column page row limits, interleaved batch coalescing and new ArrayReader/ArrayIterator concepts. Two days earlier 59.3.2 and 58.4.1 shipped with a use-after-free fix in Buffer::shrink_to_fit and other correctness backports, and 57.3.2 is also out.
What is NATS?
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
Apache Arrow Rust vs NATS: editorial side-by-side
Apache Arrow Rust
5.0DEVOPS
Arrow Rust 60.1.0 ships, redacting Parquet encryption keys and adding read-ahead planning.
◆ Current state
Arrow Rust published 60.1.0 on Oct 28, the first minor on the 60 line. It redacts Parquet encryption keys from Debug output and adds a scan_plan for read-ahead in the Parquet push decoder, a separate page-index decoder, per-column page row limits, interleaved batch coalescing and new ArrayReader/ArrayIterator concepts. Two days earlier 59.3.2 and 58.4.1 shipped with a use-after-free fix in Buffer::shrink_to_fit and other correctness backports, and 57.3.2 is also out.
◆ Where it's heading
The project ships new Parquet decoding APIs on the current major while pushing memory-safety and data-correctness fixes to three older lines, which suggests downstream engines pin old majors for long periods. The Parquet work keeps aiming at async, push-based reading with finer control over I/O.
◆ Prediction
Expect 61.0.0 on the usual major cadence, with more push-decoder and page-index APIs, while 59.x and 58.x get further backports.
NATS
5.0DEVOPS
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
◆ Current state
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
◆ Where it's heading
After 2.15's desired-state metalayer, the release stream has turned to hardening: two rounds of metalayer data-safety fixes in 2.15.1, now a batch of authorization and certificate-validation fixes. Every 2.15 patch is mirrored to 2.14, so the project is carrying two lines in parallel while 2.15 adoption grows.
◆ Prediction
Expect paired 2.15.3 / 2.14.10 candidates within a few weeks, continuing the mirrored cadence. The entries don't show when 2.14 support ends.
