Fastest Database for Agent Traces

3 followers

Zenith is an open-source columnar database in Rust, purpose-built for AI agent traces — long, sparse, high-cardinality JSON spans with rich text, late annotations, and bursty ingest. It runs on S3 + Postgres, exposes HTTP / gRPC / OTLP, speaks SQL and ZenithQL, and bakes full-text + vector + JSON-path search directly into segments (no sidecar indexes). Apache 2.0.

Hey Product Hunt Alex here from Polarity. We open-sourced ZenithDB, a Rust columnar engine for AI agent traces. We were always frustrated by the cost and latency of running agent observability on Postgres, ClickHouse, and Langfuse, so we ran investigations that led to an observation: agent traces are not the workload these backends were designed for. Spans within a trace are tightly correlated, spans across traces are not, and the hot query is "give me this whole trace, decoded," not "scan a billion rows and aggregate." Trace-locality is the right primitive for this, and globally-sorted tables are wasted at this scale. Thats why we built ZenithDB, world's fastest database for storing AI Agent Traces!
