What is Aim?

An experiment tracker grinding on storage performance — and quiet for over a year.

Aim is an open-source ML experiment tracker whose 3.2x line reads almost entirely as storage and indexing work: constant indexing of in-progress runs, reading from a single unified database, fallbacks when the index is missing, stalled-run detection. The user-facing additions in this window are narrow — a read-only UI mode, report creation, self-signed SSL support, PytorchLightning logger contexts. The most recent entry here is from May 2025, making this feed over a year stale.

What is OpenHouse?

OpenHouse adds time-zone-aware retention and per-database table caps.

OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.

Aim vs OpenHouse: editorial side-by-side

An experiment tracker grinding on storage performance — and quiet for over a year.

◆ Current state

Aim is an open-source ML experiment tracker whose 3.2x line reads almost entirely as storage and indexing work: constant indexing of in-progress runs, reading from a single unified database, fallbacks when the index is missing, stalled-run detection. The user-facing additions in this window are narrow — a read-only UI mode, report creation, self-signed SSL support, PytorchLightning logger contexts. The most recent entry here is from May 2025, making this feed over a year stale.

◆ Where it's heading

The direction across these releases is toward making the local storage layer trustworthy at scale rather than expanding what the tracker does. Repeated fixes around index corruption, empty index.db handling, false-positive metric checks, and session refresh point at users hitting durability problems on long-running or high-volume tracking. Integration surface grows only where contributors push it — S3 client config, Lightning contexts, remote mass updates all arrive as outside contributions rather than a planned roadmap.

◆ Prediction

With no release visible in over a year, the honest read is that cadence has stopped rather than shifted; the entries give no signal of a 4.x line or a direction change. If work resumes, the pattern suggests more storage-correctness fixes before any new capability.

5.0

OpenHouse adds time-zone-aware retention and per-database table caps.

◆ Current state

OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.

◆ Where it's heading

OpenHouse is adding the controls a shared lakehouse needs at scale: quotas, audit trails and retention that matches business calendars. Views are getting the same governance tables already had.

◆ Prediction

Expect more views milestones after audit (the release is labeled Views M1), and further operator controls for quotas and maintenance.
