orbital vs slider: at a glance
What is orbital?
Turning fitted tidymodels into SQL, one model family at a time — and the boosting engines just landed.
orbital converts a fitted tidymodels workflow into a database expression so prediction runs where the data lives, no R session in the loop. Its value is entirely a function of coverage, and 0.5.0 was the largest coverage release yet: catboost and lightgbm boosted trees, rpart decision trees, earth-backed MARS, glmnet multinomial regression, and both randomForest and ranger random forests, all for numeric, class, and probability predictions. The 0.5.1 follow-up is corrective, fixing SQL that Snowflake and other engines rejected because it cast booleans directly to numeric.
What is slider?
Feature-complete since 2021, and every release since has been paying CRAN's C API bill
slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.

Turning fitted tidymodels into SQL, one model family at a time — and the boosting engines just landed.
◆ Current state
orbital converts a fitted tidymodels workflow into a database expression so prediction runs where the data lives, no R session in the loop. Its value is entirely a function of coverage, and 0.5.0 was the largest coverage release yet: catboost and lightgbm boosted trees, rpart decision trees, earth-backed MARS, glmnet multinomial regression, and both randomForest and ranger random forests, all for numeric, class, and probability predictions. The 0.5.1 follow-up is corrective, fixing SQL that Snowflake and other engines rejected because it cast booleans directly to numeric.
◆ Where it's heading
The package has been working outward in rings: recipe preprocessing steps first, then model types, then post-processing via the tailor package in 0.4.0, with show_query() added so users can inspect what actually gets sent. Recent releases show the constraint shifting from R-side translation to SQL dialect compatibility — the bugs now are about what a specific database will accept, not whether a model can be expressed. estimate_orbital_size() in 0.5.1 acknowledges the other practical limit, since generated expressions can grow large enough to matter before you generate them.
◆ Prediction
With the major boosting and ensemble engines covered, expect the next releases to keep chasing dialect-specific SQL correctness across warehouses rather than adding model families.

Feature-complete since 2021, and every release since has been paying CRAN's C API bill
◆ Current state
slider provides sliding-window and index-aware window functions for R, with a C implementation underneath and a specialised fast path for common aggregations. The user-facing surface has been stable since 0.3.0 in late 2022. Everything after that is compliance and platform work: STRING_PTR removed in 0.3.2, OBJECT() removed in 0.3.3, a vctrs callable's C signature corrected, and the minimum R version raised twice.
◆ Where it's heading
Two forces set the release schedule, and neither is feature demand. The first is CRAN closing off non-API C entry points, which packages reaching into R internals for speed have to unwind one accessor at a time — slider is on its second such release with no visible loss of function. The second is vctrs, whose breaking changes slider absorbs ahead of time; 0.2.2 exists solely to prepare for one. The last release that added anything callers can see was 0.3.0's slider_plus() and slider_minus() extension hooks.
◆ Prediction
Expect the pattern to continue: another non-API accessor removal or a vctrs compatibility release, rather than new window functions. The C-level surface is the only part of this package still moving.
