OpenHouse vs Sigma Computing: at a glance
What is OpenHouse?
OpenHouse locks down its column-defaults capability flag as default values near completion.
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.
What is Sigma Computing?
Sigma is moving data modeling out of its own UI and into the terminal.
Sigma shipped a plugin for Claude Code that builds complete data models — metrics, relationships, columns, descriptions — from the terminal, alongside guidance on building Sigma Agents that handle schema discovery and model creation against Snowflake semantic views. Automated Actions landed for running reports, refreshing data, calling APIs, and triggering agents on a schedule, and embedded analytics gained bidirectional JavaScript events over postMessage.

OpenHouse

◆ Current state
OpenHouse shipped eleven builds (v0.5.529 to v0.5.539) in a week. The substantive work is a pluggable pre-commit check framework inside doCommit, built so column-default rules run on every commit path, and the first wiring of OpenHouseCatalog to the Views service. v0.5.539 makes the required-capability.column-defaults property immutable, and earlier builds added a tableExists endpoint, opt-in Spark SQL ALTER TABLE ... UNLOCK, and validation that blocks RTAS combined with WAP or replication.
◆ Where it's heading
LinkedIn's table catalog is moving business rules into the commit itself, so defaults, property rules and commit policies all reject the same way with clear 400s. Views and column default values are being built in parallel, and both are now past plumbing into user-facing guards. The team favors small, reversible steps.
◆ Prediction
Expect column default values and the Views client API to become usable end to end within the next few builds, with more PreCommitCheck rules registered by the tables service.
Sigma Computing
0.0ANALYTICS
Sigma is moving data modeling out of its own UI and into the terminal.
◆ Current state
Sigma shipped a plugin for Claude Code that builds complete data models — metrics, relationships, columns, descriptions — from the terminal, alongside guidance on building Sigma Agents that handle schema discovery and model creation against Snowflake semantic views. Automated Actions landed for running reports, refreshing data, calling APIs, and triggering agents on a schedule, and embedded analytics gained bidirectional JavaScript events over postMessage.
◆ Where it's heading
Two directions are converging on the same idea: Sigma as a system that runs without someone watching it. Automated Actions handles the scheduled half, the Claude Code plugin and agent guidance handle the authored half, and the embedding work makes Sigma a component inside someone else's application rather than a destination. The recurring argument in the writing — that read-only dashboards are no longer enough — is consistent across all three.
◆ Prediction
Expect the agent surface to extend from model creation into model maintenance, since schema drift is what makes hand-built models rot. The embedded and automation threads suggest write-back workflows will keep deepening.
