QuestDB

DEVOPS
Velocity5.0

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

questdb.io ↗

QuestDB is hardening into the time-series engine for regulated capital markets.

◆Current state
QuestDB's recent feed splits cleanly between shipping and storytelling. On the product side, two solid releases — Enterprise 3.3.1 (Parquet tiering, custom CA, column-level access control) and 9.4.2 (query sharing, new aggregates, a hardening pass) — deepen the database for demanding deployments. On the narrative side, a run of engineering deep-dives and capital-markets case studies (One Trading, Aeron) stakes out finance as the beachhead.
◆Where it's heading
The direction is rigor over flash: fewer headline features, more of what regulated, high-throughput users need — data tiering, granular permissions, deterministic replay, benchmark honesty. The blog cadence on JIT internals and benchmarking method builds technical credibility, while the case studies name the target customer (24/7 exchanges, real-time surveillance).
◆Prediction
Expect the next releases to keep filling enterprise gaps — retention/tiering controls and access management — and more finance-sector proof points rather than a new headline capability.

    The mask that compiles to nothing: how HotSpot's JIT learned to reason about bits

    An engineering deep-dive on JVM JIT internals, not a product change — part of QuestDB's steady stream of technical-credibility content rather than a shipped feature.

    Lies, Damn Lies and Database Benchmarks

    A methodology post on how benchmark framing skews results, including QuestDB's own — thought leadership, not a release. It reinforces the credibility play but changes nothing in the product.

    QuestDB Enterprise 3.3.1: storage policies, custom CA, and finer-grained access control

    A real Enterprise release: a storage-policy engine for tiering data to Parquet, a custom root CA for replication stores, and column-level GRANT/REVOKE. Squarely aimed at the regulated, high-retention deployments the case studies describe.

    QuestDB 9.4.2: shareable queries, new aggregates, and a hardening pass

    The open-source engine gains query sharing in the Web Console, the array_agg and regr_r2 aggregates, and hardening on the Parquet and posting-index paths — incremental but on the reliability track serious users need.

    Aeron and QuestDB: building open infrastructure for capital markets data

    A positioning piece on pairing QuestDB with Aeron for exactly-once, deterministic replay in capital markets — market storytelling, not a product change, but it names the target segment clearly.

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

    A customer story — a regulated 24/7 futures exchange running 1.8M orders/sec on QuestDB — that serves as a proof point for the finance push. No product change, but strong evidence of where QuestDB is landing.
