Apache Pinot vs projoint: at a glance
What is Apache Pinot?
Pinot 1.5 pushed queries across cluster boundaries; 1.5.1 was pure CVE cleanup.
Pinot releases annually-to-semiannually and packs each one densely. 1.5.0 in May carried a federation and multi-cluster routing framework, multi-stage engine work including UNNEST and enriched joins, upsert support for offline tables with commit-time compaction, Kafka 4.x, and new N-gram, IFST, and combined Lucene indexes. The only release since is 1.5.1, a security patch that changes nothing functional — dependency updates and exclusions to clear reported CVEs, with a clean scan of the binary distribution.
What is projoint?
projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.
projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

Apache Pinot
2.5INFRA · APISANALYTICS
Pinot 1.5 pushed queries across cluster boundaries; 1.5.1 was pure CVE cleanup.
◆ Current state
Pinot releases annually-to-semiannually and packs each one densely. 1.5.0 in May carried a federation and multi-cluster routing framework, multi-stage engine work including UNNEST and enriched joins, upsert support for offline tables with commit-time compaction, Kafka 4.x, and new N-gram, IFST, and combined Lucene indexes. The only release since is 1.5.1, a security patch that changes nothing functional — dependency updates and exclusions to clear reported CVEs, with a clean scan of the binary distribution.
◆ Where it's heading
Two threads run through every release in this window: the multi-stage query engine maturing toward general SQL, and the ingestion side absorbing operational realities like upserts, pauseless consumption, and rebalancing. Federation is the newer of the two — it treats a deployment as several clusters rather than one — and it is the change most likely to alter how large installations are architected. Security patching now gets its own release rather than waiting for the next minor.
◆ Prediction
Expect the federation framework to be the theme carried forward, with routing and query planning extended across clusters in the next minor. The multi-stage engine's remaining SQL gaps are the other predictable direction.
projoint
2.5INFRA · APIS
projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.
◆ Current state
projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.
◆ Where it's heading
The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.
◆ Prediction
Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
