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 TimescaleDB?

TimescaleDB 2.30 cuts LIMIT query planning time with a new DeferredChunkAppend node.

TimescaleDB is in a steady incremental release cycle, shipping monthly point releases focused on query performance and correctness. v2.30.0 introduces DeferredChunkAppend, a custom query plan node that delays chunk expansion during planning to speed up LIMIT queries on large hypertables. The surrounding releases (2.29.0–2.29.2) addressed DML chunk exclusion, security patches, and standard bug fixes.

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.

TimescaleDB 2.30 cuts LIMIT query planning time with a new DeferredChunkAppend node.

◆ Current state

TimescaleDB is in a steady incremental release cycle, shipping monthly point releases focused on query performance and correctness. v2.30.0 introduces DeferredChunkAppend, a custom query plan node that delays chunk expansion during planning to speed up LIMIT queries on large hypertables. The surrounding releases (2.29.0–2.29.2) addressed DML chunk exclusion, security patches, and standard bug fixes.

◆ Where it's heading

The pattern over this period is consistent: each minor release targets a specific query-path bottleneck (DML chunk exclusion in 2.29, LIMIT planning in 2.30) rather than feature additions. This is optimization-first development, appropriate for a mature time-series extension where users hit performance walls before they hit feature gaps. No architectural pivots visible in the recent entries.

◆ Prediction

Expect the next cycle (2.31 or 2.30.x) to continue this bottleneck-by-bottleneck approach; aggregation paths on compressed chunks are a likely target based on the pattern of prior releases.
