Apache SkyWalking vs OpenHouse: at a glance
What is Apache SkyWalking?
SkyWalking 11.0 cuts the UI out of the backend and hands it to a separate project.
Apache SkyWalking is an open-source APM and observability platform, and its recent releases have been a sustained rebuild of its own foundations. BanyanDB, its purpose-built storage engine, replaced H2 outright and was then declared large-scale ready. The Groovy DSL runtime was ripped out for an ANTLR4 and Javassist pipeline with fail-fast compilation. GenAI observability arrived as a new telemetry domain. Version 11.0.0 now removes the bundled UI from the OAP release entirely, adds TLS with certificate hot-reload across every HTTP surface, and introduces a queryAlarms GraphQL API alongside runtime rule hot-update and a live DSL debugger.
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).

SkyWalking 11.0 cuts the UI out of the backend and hands it to a separate project.
◆ Current state
Apache SkyWalking is an open-source APM and observability platform, and its recent releases have been a sustained rebuild of its own foundations. BanyanDB, its purpose-built storage engine, replaced H2 outright and was then declared large-scale ready. The Groovy DSL runtime was ripped out for an ANTLR4 and Javassist pipeline with fail-fast compilation. GenAI observability arrived as a new telemetry domain. Version 11.0.0 now removes the bundled UI from the OAP release entirely, adds TLS with certificate hot-reload across every HTTP surface, and introduces a queryAlarms GraphQL API alongside runtime rule hot-update and a live DSL debugger.
◆ Where it's heading
The consistent method is subtraction: remove the convenient default, absorb the dependency into something the project controls, then optimise it. H2 went so BanyanDB could be the only answer. Groovy went so the DSL could be compiled and type-checked. Now the UI goes so the backend can release on its own cadence. Each removal costs operators a migration and buys the project a surface it fully owns. The security and operations work in 11.0.0 — TLS everywhere, cert rotation without restart, alarm querying by entity and layer — reads as the same platform being made deployable in environments that audit these things.
◆ Prediction
With the UI decoupled and released independently, the version coupling operators previously relied on is gone; expect the project to publish compatibility guidance or a supported-version matrix between OAP and Horizon UI, since the release notes acknowledge there is no 1:1 mapping.

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.
