pkgcache vs pool
A side-by-side editorial comparison of pkgcache and pool — release velocity, themes, recent moves, and the top alternatives to consider.
pkgcache vs pool: at a glance
What is pkgcache?
The metadata cache under pak now speaks to authenticated and corporate repositories.
pkgcache maintains the package metadata cache that pak and pkgdepends build on, so its releases are about knowing where packages live and what platform they were built for. Version 2.2.4 added support for authenticated repositories through repo_auth(), the first time the cache could reach private registries directly. The releases around it track a moving target: Posit Package Manager behaviour, R Universe binaries, macOS binary availability per R version, Bioconductor version mapping, and most recently comments in DESCRIPTION and PACKAGES files following a change in R-devel.
What is pool?
Hit 1.0, relicensed to MIT, and has shipped almost nothing but dbplyr compatibility since.
pool manages database connection pools for R, and its 1.0.0 release in early 2023 was the last time it changed meaningfully: MIT relicensing, an onCreate hook for every new connection, localCheckout(), the dbplyr 2.0 interface, and a validation interval cut from 600s to 60s. The five releases since are almost entirely about staying compatible with DBI and dbplyr as those packages evolve — the most recent, 1.0.5, is a single line of forward-compatibility for dbplyr's upcoming dialect-based dispatch.

◆ Current state
pkgcache maintains the package metadata cache that pak and pkgdepends build on, so its releases are about knowing where packages live and what platform they were built for. Version 2.2.4 added support for authenticated repositories through repo_auth(), the first time the cache could reach private registries directly. The releases around it track a moving target: Posit Package Manager behaviour, R Universe binaries, macOS binary availability per R version, Bioconductor version mapping, and most recently comments in DESCRIPTION and PACKAGES files following a change in R-devel.
◆ Where it's heading
The work has shifted from CRAN-shaped assumptions toward the mixed reality of how R packages are actually distributed now — PPM snapshots, R Universe, private and authenticated registries, Bioconductor, and per-platform binaries across several R versions. Resilience is a recurring theme too: 2.2.5 makes an unreachable Bioconductor a non-fatal condition rather than a failure. MRAN's retirement, handled in 2.2.0 by resolving its prefix to PPM, is a reminder of how much of this package's job is absorbing other people's infrastructure changes.
◆ Prediction
Expect continued tracking of R-devel metadata format changes and new binary platforms as R 4.6 lands, since both already appear in 2.2.5. Further work on authenticated repository handling is the plausible follow-on, given how recently that capability arrived.
pool

Hit 1.0, relicensed to MIT, and has shipped almost nothing but dbplyr compatibility since.
◆ Current state
pool manages database connection pools for R, and its 1.0.0 release in early 2023 was the last time it changed meaningfully: MIT relicensing, an onCreate hook for every new connection, localCheckout(), the dbplyr 2.0 interface, and a validation interval cut from 600s to 60s. The five releases since are almost entirely about staying compatible with DBI and dbplyr as those packages evolve — the most recent, 1.0.5, is a single line of forward-compatibility for dbplyr's upcoming dialect-based dispatch.
◆ Where it's heading
This is a component that has reached its useful shape and now moves only when the packages around it move. Every post-1.0 entry is either a dependency floor being raised, a generic being wrapped, or an example being rewritten. The one thing worth watching is that pool has to implement each new dbplyr and DBI generic by hand, so its release cadence is set by that upstream surface rather than by its own roadmap.
◆ Prediction
The next release will almost certainly be another dbplyr or DBI compatibility pass, most likely completing the dialect-based dispatch work that 1.0.5 prepared for. Nothing in these entries suggests new pooling capability is planned.
