What is Zeebe?

Camunda's 8.10 alpha is one feature carried across every API surface at once.

The alpha4 tag is dominated by Late Business ID Assignment: a protocol definition, engine support for assigning the ID via CompleteJob, forward-propagation semantics, REST and gRPC endpoints, a Java client, and exporter changes so secondary storage reflects it. The rest of the window is process rather than product, with a release candidate carrying a single CI spec-check fix and a maintenance tag backporting dependency bumps to the 8.7 Optimize branch.

What is QuestDB?

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

QuestDB just shipped 10.0, its first major version bump in the visible window, built around QWP — a binary columnar wire protocol that handles writes going in and streams Arrow back out through a single client. The release also carries live views in beta, notebooks driven by coding agents, and the storage groundwork that QuestDB Enterprise 4.0 builds cold storage on. The days since have been spent substantiating it: a parallel-reader benchmark puts 500M rows into Arrow in 2.3 seconds against ClickHouse and TimescaleDB. Around the releases, the feed is mostly engineering deep-dives, capital-markets case studies, and comparison guides.

Zeebe vs QuestDB: editorial side-by-side

Z
Zeebe
DEVOPS
5.0

Camunda's 8.10 alpha is one feature carried across every API surface at once.

◆ Current state

The alpha4 tag is dominated by Late Business ID Assignment: a protocol definition, engine support for assigning the ID via CompleteJob, forward-propagation semantics, REST and gRPC endpoints, a Java client, and exporter changes so secondary storage reflects it. The rest of the window is process rather than product, with a release candidate carrying a single CI spec-check fix and a maintenance tag backporting dependency bumps to the 8.7 Optimize branch.

◆ Where it's heading

The pattern is a workflow engine treating its protocol as the unit of work: a capability is not shipped until the engine, both transports, the client library, and the exporters all express it. That discipline is why one feature accounts for an entire alpha. Alongside it, older minor lines keep receiving dependency and security backports on their own tags, so the release stream mixes forward work and long-tail maintenance.

◆ Prediction

Late Business ID Assignment currently arrives through CompleteJob with forward propagation; the entries suggest the remaining work is exposing it on the other lifecycle operations rather than starting a new capability before 8.10 stabilizes.

6.3

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

◆ Current state

QuestDB just shipped 10.0, its first major version bump in the visible window, built around QWP — a binary columnar wire protocol that handles writes going in and streams Arrow back out through a single client. The release also carries live views in beta, notebooks driven by coding agents, and the storage groundwork that QuestDB Enterprise 4.0 builds cold storage on. The days since have been spent substantiating it: a parallel-reader benchmark puts 500M rows into Arrow in 2.3 seconds against ClickHouse and TimescaleDB. Around the releases, the feed is mostly engineering deep-dives, capital-markets case studies, and comparison guides.

◆ 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 — 33M rows/s on one machine at a million series, roughly 3.6x ILP over a network — and 10.0 turns that from a benchmark argument into the default path in and out. The follow-up post shifts the argument to the read side, which is the half QWP actually changes: folding Arrow egress into the same protocol points the database at the Python analytics stack directly rather than through a SQL driver, something the Polars and ConnectorX content has been rehearsing for months. Live views and agent notebooks are earlier-stage, and the Enterprise line continues on its own track.

◆ Prediction

Expect QuestDB Enterprise 4.0 next, built on 10.0's storage work and leading with cold storage, plus client libraries catching up to QWP one language at a time. Live views and the agent notebooks look likeliest to leave beta on a later minor rather than in the next release.
