What is QuestDB?
QuestDB 10.0 ships QWP — a binary protocol unifying ingestion and Arrow reads — while Enterprise 4.0 adds cold storage and hot failover.
QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.
What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

QuestDB

QuestDB 10.0 ships QWP — a binary protocol unifying ingestion and Arrow reads — while Enterprise 4.0 adds cold storage and hot failover.
◆ Current state
QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.
◆ Where it's heading
QuestDB is positioning itself as the time-series database that fits into modern lakehouse architectures without requiring ETL. QWP + Arrow + cold storage + Iceberg compatibility all point toward a single goal: a streaming time-series engine that speaks natively to Parquet-based analytics stacks. The blog post explaining Parquet/Iceberg positioning is the clearest signal — the team is selling to data engineers building lakehouses, not just ops engineers running dashboards.
◆ Prediction
The cold storage Iceberg integration will deepen with catalog support and query pushdown for Spark and Trino. QWP client libraries will ship for major languages beyond the initial Python/Java coverage.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
