QuestDB

DEVOPS
Velocity5.0

High-performance time-series database for real-time analytics

QuestDB doubles down on capital-markets workloads while pushing query speed and Parquet tiering.

Current state
QuestDB is a time-series database iterating quickly on the engine: recent releases add a posting index for SYMBOL columns, parallel/vectorized WINDOW JOIN, lateral joins and UNNEST, shareable queries in the Web Console, and an Enterprise storage-policy engine for tiering data to Parquet with column-level access control. Its changelog feed mixes these releases with benchmark essays and capital-markets case studies.
Where it's heading
The product is leaning hard into financial and capital-markets use cases — case studies on regulated futures exchanges, Aeron integration for deterministic replay — while the engine work concentrates on analytical performance and open formats (Parquet). Enterprise features (storage tiering, custom CA, granular grants) target larger, regulated deployments.
Prediction
Expect continued engine performance work and Parquet/tiering investment, with capital markets remaining the lead vertical in both features and go-to-market storytelling.

    Aeron and QuestDB: building open infrastructure for capital markets data

    A technical piece on pairing Aeron with QuestDB for capital-markets data is positioning content rather than a shipped feature, underscoring the financial-vertical focus.

    One Trading runs a regulated 24/7 futures exchange on QuestDB

    A customer case study on One Trading running a regulated futures exchange on QuestDB is go-to-market storytelling, not a product change — though the throughput figures reinforce the capital-markets pitch.
