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 Zeebe?

Camunda's 8.10 alpha threads business IDs through the stack while the tag feed fills with CI noise.

Zeebe's public tag stream is dominated by monorepo automation: renovate dependency bumps, backport tags and CI hardening published as `0.0.0-dryrun-*` releases. The substantive work sits in the 8.10.0-alpha4 line, where late business ID assignment landed across the engine, REST, gRPC and the Java client at once. Maintenance branches 8.7 through 8.9 continue to take security and stability backports in parallel.

QuestDB vs Zeebe: 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.

Zeebe
DEVOPS
5.0

Camunda's 8.10 alpha threads business IDs through the stack while the tag feed fills with CI noise.

◆ Current state

Zeebe's public tag stream is dominated by monorepo automation: renovate dependency bumps, backport tags and CI hardening published as `0.0.0-dryrun-*` releases. The substantive work sits in the 8.10.0-alpha4 line, where late business ID assignment landed across the engine, REST, gRPC and the Java client at once. Maintenance branches 8.7 through 8.9 continue to take security and stability backports in parallel.

◆ Where it's heading

Camunda is building 8.10 as a correlation-identity release: business IDs propagate from job completion through the engine into secondary storage, which is the groundwork for tracing a process instance by a domain key rather than an internal one. The alpha4 line has now moved from rc1 through rc2 to a full alpha with the same feature set, so the surface is stabilising rather than expanding. Four supported branches receiving concurrent backports signals the enterprise support burden is shaping release cadence as much as new capability.

◆ Prediction

Expect 8.10.0-alpha5 or a beta that consolidates the business ID surface and starts exercising it in Operate and Tasklist queries. Whether anything beyond business IDs is targeted for 8.10 is not visible in these entries.
