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 Splunk?

Splunk's changelog feed is mostly marketing pages and nav — actual release news is buried in the blog.

What surfaces from Splunk in this slice is marketing and documentation index content: Splunk Enterprise positioning, the InfoSec starter app, the Compatibility Matrix page, the home navigation, and a 'Latest Articles' index on the observability blog. The blog index does mention real product activity — OpenTelemetry eBPF Instrumentation in the Splunk Distribution of the OpenTelemetry Collector, OTLP log ingestion, ITSI Content Pack for Cisco Data Center Networking — but the substance lives behind those headlines, not in this feed.

QuestDB vs Splunk: editorial side-by-side

Q

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.

1.0

Splunk's changelog feed is mostly marketing pages and nav — actual release news is buried in the blog.

◆ Current state

What surfaces from Splunk in this slice is marketing and documentation index content: Splunk Enterprise positioning, the InfoSec starter app, the Compatibility Matrix page, the home navigation, and a 'Latest Articles' index on the observability blog. The blog index does mention real product activity — OpenTelemetry eBPF Instrumentation in the Splunk Distribution of the OpenTelemetry Collector, OTLP log ingestion, ITSI Content Pack for Cisco Data Center Networking — but the substance lives behind those headlines, not in this feed.

◆ Where it's heading

From this slice it's hard to read actual product trajectory. The breadcrumbs in the blog index point toward Splunk doubling down on OpenTelemetry as the ingestion surface (eBPF instrumentation, OTLP log ingest), broader Kubernetes monitoring coverage, and ITSI content packs for networking. Nothing here suggests a strategic shift; the work pattern is observability-feature breadth and OpenTelemetry alignment.

◆ Prediction

Until a release-notes channel feeds into this view, predictions are general. Based on the blog index, expect more OpenTelemetry-aligned ingestion improvements, additional ITSI content packs for major infrastructure categories, and continued AI-observability messaging tied to KubeCon EU 2026. A formal Splunk Enterprise release announcement is also likely soon given the Compatibility Matrix and release-notes pages being actively maintained.
