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 NSD?

NSD patched 8 CVEs across two dedicated security releases and added EDNS0 padding and PROXYv2 access controls.

NSD released three significant versions in quick succession: 4.15.1 fixed four CVEs including a TCP-window-throttle DoS, a UDP cookie-option DoS, an IP ACL bypass for some address ranges, and a PROXYv2 port ACL bypass. 4.15.2 followed with feature additions — HHIT/BRID RR type support, new SVCB service parameter keys (docpath, pvd, oots), EDNS0 padding over TLS per RFC 7830/8467, and configurable PROXYv2 access control — alongside another substantial round of hardening fixes, many reported by Palo Alto Networks. The 4.15.0 release introduced a breaking change to Prometheus metrics, moving zone names from metric labels to label values.

Apache Arrow Rust vs NSD: editorial side-by-side

A6.3

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.

5.0

NSD patched 8 CVEs across two dedicated security releases and added EDNS0 padding and PROXYv2 access controls.

◆ Current state

NSD released three significant versions in quick succession: 4.15.1 fixed four CVEs including a TCP-window-throttle DoS, a UDP cookie-option DoS, an IP ACL bypass for some address ranges, and a PROXYv2 port ACL bypass. 4.15.2 followed with feature additions — HHIT/BRID RR type support, new SVCB service parameter keys (docpath, pvd, oots), EDNS0 padding over TLS per RFC 7830/8467, and configurable PROXYv2 access control — alongside another substantial round of hardening fixes, many reported by Palo Alto Networks. The 4.15.0 release introduced a breaking change to Prometheus metrics, moving zone names from metric labels to label values.

◆ Where it's heading

NSD is in a security-intensive maintenance phase with a consistent external contributor: Qifan Zhang at Palo Alto Networks has reported the majority of bugs fixed in the 4.15.x cycle, including heap overflows, assertion failures on malformed records, and multiple DoS vectors. This external security research pressure is accelerating the quality of NSD's defensive posture. Protocol completeness work (new RR types, SVCB parameters) continues alongside the security fixes.

◆ Prediction

The PROXYv2 improvements suggest NSD deployments behind TLS-terminating load balancers are a growing use case — expect additional configuration controls for encrypted-DNS setups. The experimental multi-catalog-consumer-zones flag may graduate to stable in a future release.
