BigQuery vs eratosthenes
A side-by-side editorial comparison of BigQuery and eratosthenes — release velocity, themes, recent moves, and the top alternatives to consider.
BigQuery vs eratosthenes: at a glance
What is BigQuery?
BigQuery is making itself agent-callable and pulling inference inside the SQL boundary.
Two GA milestones define the current position: the BigQuery MCP server, and the managed AI functions AI.IF, AI.SCORE and AI.CLASSIFY that run Gemini from inside a query. Alongside them, BigQuery Graph entered preview, and a steady GA cadence continues across sharing listings, materialized views over CDC tables, Snowflake transfers, code-asset folders and Dataform's strict act-as enforcement.
What is eratosthenes?
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().

◆ Current state
Two GA milestones define the current position: the BigQuery MCP server, and the managed AI functions AI.IF, AI.SCORE and AI.CLASSIFY that run Gemini from inside a query. Alongside them, BigQuery Graph entered preview, and a steady GA cadence continues across sharing listings, materialized views over CDC tables, Snowflake transfers, code-asset folders and Dataform's strict act-as enforcement.
◆ Where it's heading
The warehouse is being repositioned as something agents call and models run inside, not a destination that pipelines feed. MCP handles the calling side; the AI functions handle the execution side; strict act-as and folder-level access handle the governance the first two make urgent.
◆ Prediction
Expect the governance layer to develop fastest from here — finer control over what an agent can query and what inference it may run — since that is the constraint GA on both fronts now exposes.

eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
◆ Current state
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().
◆ Where it's heading
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.
◆ Prediction
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.

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

dqcheckr adds drift analysis, then removes the YAML a user had to hand-write.

An actuarial mainstay spends its releases on CI plumbing, not on new mathematics.
EDAForge
EDAForge is a data-quality auditor renamed mid-flight, still finding its CRAN footing.
