Dagster vs OpenHouse: at a glance
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 OpenHouse?
LinkedIn's Iceberg control plane, shipping one pull request per release.
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
Dagster vs OpenHouse: editorial side-by-side
Dagster
6.3ANALYTICS
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.
OpenHouse
5.0ANALYTICS
LinkedIn's Iceberg control plane, shipping one pull request per release.
◆ Current state
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
◆ Where it's heading
The theme across these releases is treating table metadata as something that must not be lost by accident, and making failures attributable. Policies now merge rather than being rebuilt from the request. Data loader errors carry a request ID and distinguish authentication from transport failure instead of retrying auth errors as transient. Feature toggles gained self-service table overrides so server-side ramps and table-owner opt-in can coexist.
◆ Prediction
The jobs-observability plan explicitly defers OTEL gauges, a heartbeat sampler, and DLQ counters to a later phase, so those are the concrete next steps visible in these entries.
