What is QuestDB?

QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.

QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.

What is SciPy?

SciPy finished translating itself out of Fortran and now offers a Fortran-free build.

SciPy ships on a six-month major cadence with a long release-candidate tail, and the 1.17/1.18 cycle has been dominated by three structural projects rather than new algorithms. The Fortran-to-C translation is complete, with an experimental Fortran-free build now available to developers. ILP64 BLAS and LAPACK went from initial support in 1.17.0 to three fully supported build modes in 1.18.0. And array API work has spread far enough that stats functions now run under JAX JIT and accept lazy arrays.

QuestDB vs SciPy: editorial side-by-side

Q
QuestDB
DEVOPS
6.3

QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.

◆ Current state

QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.

◆ Where it's heading

The protocol work is the thread that matters. QuestDB has been positioning against InfluxDB Line Protocol on ingestion throughput for a while, and 10.0 turned that from a benchmark argument into the default path both in and out of the database. The follow-up posts are consolidation rather than new capability: the same protocol re-explained for a different reader each time, which is what a project does when it needs an ecosystem to adopt a format. Live views and agent-driven notebooks remain the less-proven half of the release.

◆ Prediction

Expect client libraries and third-party connectors to be the next visible work, since a proprietary wire protocol is only worth its switching cost once the dataframe tools speak it. Whether live views leave beta is not something these entries settle.

0.0

SciPy finished translating itself out of Fortran and now offers a Fortran-free build.

◆ Current state

SciPy ships on a six-month major cadence with a long release-candidate tail, and the 1.17/1.18 cycle has been dominated by three structural projects rather than new algorithms. The Fortran-to-C translation is complete, with an experimental Fortran-free build now available to developers. ILP64 BLAS and LAPACK went from initial support in 1.17.0 to three fully supported build modes in 1.18.0. And array API work has spread far enough that stats functions now run under JAX JIT and accept lazy arrays.

◆ Where it's heading

SciPy is decoupling itself from its own foundations — the Fortran toolchain, the assumption of 32-bit indexing, and the assumption that arrays are NumPy arrays. Each of those makes SciPy buildable and usable in places it previously was not: environments without a Fortran compiler, problems above the LP64 size limit, and accelerator-backed array libraries. The internal FFT backend swap from pocketfft to ducc0 fits the same pattern of replacing inherited machinery.

◆ Prediction

The Fortran-free build should move from developer-testing toward a supported option as feedback comes in, and array API coverage will likely keep expanding function by function, as it has each release.
