What is immudb?

immudb 1.11.0 added PostgreSQL compatibility — tamper-evident storage now accessible to ORM-based stacks.

immudb is in a 1.11.x maintenance cycle after the substantial 1.11.0 release, which added PostgreSQL ORM compatibility (pg_catalog, information_schema), structured audit logging with tamper-proof JSON events, and a new --audit-verif flag. The 1.11.2 maintenance release fixes a transaction survival issue when a statement fails before execution — a correctness fix for edge cases in transaction handling. The v2.0.0-RC1 from early 2025 introduced a different architecture (new indexing layer, simplified API), but 1.11.x appears to be the active production track.

What is Weaviate?

Weaviate is chasing retrieval quality past the vector, into documents people actually store

Weaviate publishes engineering writing alongside its releases. The 1.39 release brought the Boost API and MMR to general availability with a Search REST API in preview, and separate posts have covered query profiling to show where a slow query spends its time and test-time compute scaling in search mode. The newest post takes on charts and tables in documents — the content that defeats naive text extraction before a vector database ever sees it.

immudb 1.11.0 added PostgreSQL compatibility — tamper-evident storage now accessible to ORM-based stacks.

◆ Current state

immudb is in a 1.11.x maintenance cycle after the substantial 1.11.0 release, which added PostgreSQL ORM compatibility (pg_catalog, information_schema), structured audit logging with tamper-proof JSON events, and a new --audit-verif flag. The 1.11.2 maintenance release fixes a transaction survival issue when a statement fails before execution — a correctness fix for edge cases in transaction handling. The v2.0.0-RC1 from early 2025 introduced a different architecture (new indexing layer, simplified API), but 1.11.x appears to be the active production track.

◆ Where it's heading

The PostgreSQL compatibility push is the clearest directional signal: immudb is trying to become accessible to developers using standard ORMs without learning immudb's native API. Combined with the structured audit logging, the pitch is a tamper-evident backend that behaves like PostgreSQL for existing toolchains. The v2.0.0 architecture rework remains an open question — whether it reaches GA or gets merged back into the 1.x line is unclear from the releases shown.

◆ Prediction

A stable v2.0.0 release or clear abandonment of the v2 branch in favor of continued 1.x enhancements is the next decision point. The PostgreSQL compatibility work will likely expand to cover more pg_catalog views needed by common ORMs.

Weaviate is chasing retrieval quality past the vector, into documents people actually store

◆ Current state

Weaviate publishes engineering writing alongside its releases. The 1.39 release brought the Boost API and MMR to general availability with a Search REST API in preview, and separate posts have covered query profiling to show where a slow query spends its time and test-time compute scaling in search mode. The newest post takes on charts and tables in documents — the content that defeats naive text extraction before a vector database ever sees it.

◆ Where it's heading

The work keeps moving up the retrieval stack. First the database primitives, then the diagnostics that show why a query is slow, then re-ranking and test-time compute to improve what comes back, and now the ingestion problem of getting meaning out of non-prose content. Running alongside is a product diary series about building Foundry, which is where the company writes about applying its own stack rather than about the engine.

◆ Prediction

Chart and table extraction is being argued in the blog while the engine work stays on search quality, so expect the ingestion side to become tooling rather than advice — a supported path for structured content, not just a post explaining the problem.
