LaunchDarkly vs rgm: at a glance
What is LaunchDarkly?
LaunchDarkly is moving experiment analysis into the customer's own warehouse.
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.
What is rgm?
A microbiome network model that got itself un-archived by deleting the dependency that killed it.
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.

LaunchDarkly is moving experiment analysis into the customer's own warehouse.
◆ Current state
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.
◆ Where it's heading
The experimentation story is the one that matters. Rather than pulling customer event data into LaunchDarkly to analyse it, LaunchDarkly is computing where the data already lives — which sidesteps the data-movement and governance objections that stall experimentation platforms in larger companies. Shipping Redshift and Databricks back to back, then immediately adding connection health checks, is the pattern of a capability being made operational rather than demonstrated.
◆ Prediction
Expect the remaining major warehouses to follow the same integration pattern, and more tooling around connection reliability as the warehouse becomes a dependency in the experiment path. The SDK rewrite suggests the other client SDKs will be consolidated onto the same JavaScript core.

A microbiome network model that got itself un-archived by deleting the dependency that killed it.
◆ Current state
rgm implements the random graphical model for microbiome interactions across related environments, published in JABES in 2026. The package was archived from CRAN in February 2026 because of its dependency on huge; the recovery release drops that dependency entirely, which cost it the graphical-lasso warm start that used to seed the initial graph — the default is now an empty graph, with warm starts left to the user. A post-processing function returning ggplot diagnostics arrived in the same release.
◆ Where it's heading
Three tags shipped inside two hours on one day, and the notes are candid about why: 1.1.0 held the actual work but was never released, 1.2.0 restated it under a higher version to signal the size of the change, and 1.2.1 answered CRAN pre-test feedback. Beyond the archival recovery, the visible work is housekeeping that had accumulated — a shadowed rmvnorm() definition, roxygen import tags that were silently emitting nothing, leftover C++ template scaffolding, and build artifacts under version control. The diagnostics function is the only genuinely new user-facing capability in the window.
◆ Prediction
The immediate task was restoring availability, and that is done; the open question the entries raise is whether losing the graphical-lasso warm start affects convergence in practice, which the new diagnostic plots are positioned to answer.
