X12I · COUNTEX
Pre-aggregate arbitrary JSON events into query-ready counters
Define CounterMaps once, ingest at event time, and serve counts, measures, rankings, forecasts, and operational rollups without rescanning raw events.

Install for agents & tooling
Knowledge SDK — install as a devDependency only (not a production runtime).
npm i -D @x12i/countex-docsWhat Countex gives you
Generic event mapping
Map arbitrary JSON paths into scope, subjects, metrics, dimensions, timeframes, deltas, and measures.
Sparse pre-aggregation
Store only observed cells so read cost follows the requested rollup, not raw event volume.
Durable plus fast storage
Use MongoDB for durable truth, Redis for hot reads, or memory for tests and local workflows.
Insights and simulation
Rank, compare, detect anomalies, forecast, advise, and estimate capacity over the same counter model.
