EVOLVABLE · TEMPORAL · IMMUTABLE

τ (tau)

Temporal database engineered around new primitives.

Event-sourcing meets periodic and point in time travel, with addressable lenses providing view and migration like power without the complexity.

Time is hard. It's easier with the right tools.

An immutable delta valid for an explicit time range. Store only what changed, when it changed—never lose history, never duplicate state.

An ordered collection of related Taus. Reconstruct any point in time by replaying deltas—deterministic, auditable, always consistent.

A grouping of schedules that belong together. Organize related time-series data with clear boundaries and composable structure.

A transformation that acts as both view and migration. Define once, auto-evolve forever—like symlinks for your data model.

Traditional databases force you to choose. Tau makes the hard problems disappear.

Point-in-time and periodic queries are first-class operations, not slow workarounds. Query any moment with millisecond precision.

Lenses transform data without migrations or downtime. Add views, change schemas—all while serving production traffic.

Full audit trail and deterministic replay built in. Every state change is traceable, every query reproducible.

Store deltas, not duplicates. Temperature changed 0.1°? Store 0.1, not the whole record. Efficiency without complexity.

Explicit time ranges and immutability mean no lost data, no race conditions, no ambiguous state. Just clarity.

Append-only architecture means safe replication, trivial backups, and confidence in your data's integrity over time.

Audit trails, transaction history, and compliance reporting without custom event stores.

Efficient storage of periodic data with smart delta compression and native time queries.

Deterministic replay and state reconstruction for scientific computing and analysis.

Immutable logs and event sourcing primitives that make consistency tractable.
