What is OpenHouse?

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

What is OpenCTI?

OpenCTI ships FIPS-validated base images and a new vulnerability data model, targeting enterprise and government deployments.

OpenCTI is in a high-cadence operational hardening phase, releasing every 2–4 days. The recent window shows three parallel tracks: enterprise compliance (FIPS 140-3 validated Python/Node base image), platform-wide design unification (Filigran Design System v1 rollout), and data model expansion (new vulnerability module, score fields on threat actor and malware entities). The AI chatbot 'Ask Ariane' received multiple crash fixes, and a prior release added human-in-the-loop tool approval — signs that the AI analysis layer is maturing from experimental to production-grade.

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

◆ Current state

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

◆ Where it's heading

The entityType discriminator in v0.5.490 is the most directional move in this window — it creates the data model prerequisite for treating views as first-class entities alongside tables, something OpenHouse has not supported. Storage lifecycle work is converging on Iceberg-native mechanisms, reducing custom expiration logic. The post-commit operations framework in v0.5.492 is infrastructure that will allow OpenHouse to add downstream hooks (compaction triggers, notifications) without catalog coupling.

◆ Prediction

Iceberg view read support will arrive in the next several releases, building on the discriminator and HTS scaffolding now in place. The authorization model for views will be an open question — watch whether they reuse the table ACL path or introduce a parallel model.

6.3

OpenCTI ships FIPS-validated base images and a new vulnerability data model, targeting enterprise and government deployments.

◆ Current state

OpenCTI is in a high-cadence operational hardening phase, releasing every 2–4 days. The recent window shows three parallel tracks: enterprise compliance (FIPS 140-3 validated Python/Node base image), platform-wide design unification (Filigran Design System v1 rollout), and data model expansion (new vulnerability module, score fields on threat actor and malware entities). The AI chatbot 'Ask Ariane' received multiple crash fixes, and a prior release added human-in-the-loop tool approval — signs that the AI analysis layer is maturing from experimental to production-grade.

◆ Where it's heading

The combination of FIPS compliance, accessibility hardening, and enterprise-grade session key management signals a deliberate push toward government and regulated-sector deployments. The vulnerability module and inference rules that propagate vulnerability data across the knowledge graph suggest OpenCTI is building toward a more automated threat-correlation engine rather than just a data store.

◆ Prediction

Ask Ariane's human-in-the-loop approval will likely move from opt-in to default as the team gains confidence in the AI tool set. Watch for more inference rules that auto-link threat entities, and for the vulnerability module to grow into a first-class surface with dedicated views and reporting.
