The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.
A side-by-side editorial comparison of Apache Pinot and eratosthenes — release velocity, themes, recent moves, and the top alternatives to consider.
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.
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().

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.
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.

The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. Apache Pinot and eratosthenes are shipping at a similar cadence (velocity 2.5 vs 2.5, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity.
