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 Svelte?

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

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.

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

◆ Current state

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

◆ Where it's heading

The major is arriving as a consolidation rather than a rewrite: most of what lands in 3.0 was previewed in the 2.x line first, so the upgrade cost stays low by design. The centre of gravity has been remote functions and forms for six straight months, and Kit 3 mostly finalises that surface while pruning the configuration story. With breaking changes now frozen, the work shifts from designing the major to getting the ecosystem - adapters, language tools, community plugins - onto it.

◆ Prediction

The stable SvelteKit 3 release is the next milestone, and the team has tied it to RC feedback rather than a date. Expect the monthly digests to fill with adapter and tooling updates catching up to the vite.config.ts requirement before that lands.
