Levels

Levels is a high-performance time-series database purpose-built for order book and market data. It ingests raw market events, compacts them through an event-sourcing pipeline, and serves queryable historical data across multiple storage tiers.

Key Features

  • Multi-level storage — Raw, Aggregated, Period, and Resampled file tiers with automatic promotion
  • Event sourcing compaction — Replays order book events to produce compact aggregated files with synthetic snapshots
  • Schema code generation — Define a .fbs schema, generate typed record structs in C#, Python, TypeScript, or C++
  • Cross-language binary format — Identical on-disk format readable from any supported language
  • Export — CSV, Parquet, and Avro export via CLI or Web API
  • CLI tooling — Inspect files, run compaction, generate code, resample, and export from the command line
  • Backpressure management — Channel-based flow control with configurable limits
  • Data integrity — CRC32 checksums on every record, schema ID validation in file headers
