What is Dagster?

Dagster's declarative automation grows past assets while the UI is rebuilt for scale.

Dagster ships weekly 1.13.x point releases, each pairing a short list of new capability with a longer list of fixes. The through-line is Declarative Automation, the asset-condition system that separates Dagster from schedule-driven orchestrators, which has now reached jobs. Running alongside it is a sustained effort to keep the UI responsive in workspaces whose asset graphs outgrew the original interface.

What is NetObserv?

NetObserv is layering TLS visibility and health alerting on top of its eBPF flow pipeline.

NetObserv ships roughly monthly as a coordinated bundle — operator, eBPF agent, flowlogs-pipeline and console plugin move together in each release. The functional work over these six releases splits three ways: a TLS visibility feature that arrived as a knob in 1.11.3 and has been extended with metrics and alerts since, a Network Health layer built on Prometheus recording rules rather than alerts alone, and steady hardening of the agent-to-pipeline path (mTLS, hot-reload filters, packet translation and sampling fixes). Prometheus is now on by default.

6.3

Dagster's declarative automation grows past assets while the UI is rebuilt for scale.

◆ Current state

Dagster ships weekly 1.13.x point releases, each pairing a short list of new capability with a longer list of fixes. The through-line is Declarative Automation, the asset-condition system that separates Dagster from schedule-driven orchestrators, which has now reached jobs. Running alongside it is a sustained effort to keep the UI responsive in workspaces whose asset graphs outgrew the original interface.

◆ Where it's heading

Automation is escaping the asset boundary. Conditions can now launch jobs, which brings the declarative model to the parts of a deployment that never fit the asset abstraction and where users fell back to schedules. Several consecutive releases also spend their effort on virtualized lists, bounded previews and scoped search — the signature of a product whose largest customers hit the UI's limits first. Preview flags on both the job automation and the Snowflake component indicate neither is finished.

◆ Prediction

Expect Declarative Automation for jobs to move from preview to general availability within the 1.13.x line, and more first-party Components covering the remaining warehouse and dbt paths.

2.5

NetObserv is layering TLS visibility and health alerting on top of its eBPF flow pipeline.

◆ Current state

NetObserv ships roughly monthly as a coordinated bundle — operator, eBPF agent, flowlogs-pipeline and console plugin move together in each release. The functional work over these six releases splits three ways: a TLS visibility feature that arrived as a knob in 1.11.3 and has been extended with metrics and alerts since, a Network Health layer built on Prometheus recording rules rather than alerts alone, and steady hardening of the agent-to-pipeline path (mTLS, hot-reload filters, packet translation and sampling fixes). Prometheus is now on by default.

◆ Where it's heading

The project is moving from flow collection toward opinionated health signalling — recording rules, runbook links in alerts, ingress 5xx and latency templates, health metadata driving console plugin config. That is the shape of a tool trying to answer 'is the network healthy' rather than only 'what traffic occurred'. In parallel, supply-chain and workflow security is getting real attention: SBOM generation and artifact signing, SHA-pinned GitHub Actions, pwn-request workflow checks and a pprof exposure fix all landed in the last two releases. The operator was also renamed from network-observability-operator to netobserv-operator.

◆ Prediction

Expect the TLS thread to keep extending — the sequence so far is fields, then metrics, then alerts, so dashboards and health rules built on TLS data are the natural next step. Continued investment in the Network Health rule set is the other safe bet, since it is where the last three releases have concentrated their non-dependency commits.
