Apache Airflow vs Harbor: at a glance
What is Apache Airflow?
Airflow's Go, Java and TypeScript SDKs all reach 1.0 on the same day.
On November 13 Apache Airflow released stable 1.0.0 SDKs for Java, TypeScript and Go within an hour. The Java SDK authors Dags natively, with dependencies, task groups, branching, Dag triggers and the Variable and task state APIs, serialized to the same format as Python Dags. The Go and TypeScript 1.0 releases are mostly last fixes after their betas. The Amazon provider 9.40.0 also went final.
What is Harbor?
Harbor backports security hardening to 2.15 while 2.16 nears GA.
Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The 2.16.0 candidates are its first feature release in that window, with arm64 builds, custom project roles, proxy-cache filters, referrer API proxying and Valkey caching. 2.15.5-rc1 brings the same period's hardening to the older line: size limits on audited and manifest request bodies, redacted URLs in error messages, a fix for replication filters and updated Trivy and Go versions.
Apache Airflow vs Harbor: editorial side-by-side
Apache Airflow
7.5INFRA · APIS
Airflow's Go, Java and TypeScript SDKs all reach 1.0 on the same day.
◆ Current state
On November 13 Apache Airflow released stable 1.0.0 SDKs for Java, TypeScript and Go within an hour. The Java SDK authors Dags natively, with dependencies, task groups, branching, Dag triggers and the Variable and task state APIs, serialized to the same format as Python Dags. The Go and TypeScript 1.0 releases are mostly last fixes after their betas. The Amazon provider 9.40.0 also went final.
◆ Where it's heading
Airflow 3.4 made non-Python Dags possible as an experiment; a week later the language SDKs are declared stable. The project is turning its scheduler into a runtime that teams in Java, Go and TypeScript shops can adopt without writing Python. Provider releases keep their usual batched cadence underneath.
◆ Prediction
Expect the experimental Dag Importer and Task Loops from 3.4 to move toward stable in a 3.5 release, and SDK patch releases as first production users report issues.
Harbor
5.0INFRA · APIS
Harbor backports security hardening to 2.15 while 2.16 nears GA.
◆ Current state
Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The 2.16.0 candidates are its first feature release in that window, with arm64 builds, custom project roles, proxy-cache filters, referrer API proxying and Valkey caching. 2.15.5-rc1 brings the same period's hardening to the older line: size limits on audited and manifest request bodies, redacted URLs in error messages, a fix for replication filters and updated Trivy and Go versions.
◆ Where it's heading
Three candidates in two weeks suggest 2.16.0 is close to final. The release moves Harbor toward multi-arch and finer access control after a quarter of security-only work.
◆ Prediction
Expect 2.16.0 GA within one to two weeks, followed by matching 2.15.x and 2.14.x patch releases.
