What is QuestDB?
QuestDB doubles down on capital-markets workloads while pushing query speed and Parquet tiering.
QuestDB is a time-series database iterating quickly on the engine: recent releases add a posting index for SYMBOL columns, parallel/vectorized WINDOW JOIN, lateral joins and UNNEST, shareable queries in the Web Console, and an Enterprise storage-policy engine for tiering data to Parquet with column-level access control. Its changelog feed mixes these releases with benchmark essays and capital-markets case studies.
What is Rivet?
Rivet is rebuilding its actor backend into managed infrastructure for AI agents.
Rivet ships an actor-model backend - durable per-actor state, SQLite, queues - and is now stacking AI-agent infrastructure on top of it: agentOS (WASM micro-VMs for running coding agents), Secure Exec (isolated process execution), and SDKs in Rust and Effect. The pace is unusual: five 'Introducing' releases in ten days. The core is being rewritten in Rust as it goes.

QuestDB
5.0DEVOPS
QuestDB doubles down on capital-markets workloads while pushing query speed and Parquet tiering.
◆ Current state
QuestDB is a time-series database iterating quickly on the engine: recent releases add a posting index for SYMBOL columns, parallel/vectorized WINDOW JOIN, lateral joins and UNNEST, shareable queries in the Web Console, and an Enterprise storage-policy engine for tiering data to Parquet with column-level access control. Its changelog feed mixes these releases with benchmark essays and capital-markets case studies.
◆ Where it's heading
The product is leaning hard into financial and capital-markets use cases — case studies on regulated futures exchanges, Aeron integration for deterministic replay — while the engine work concentrates on analytical performance and open formats (Parquet). Enterprise features (storage tiering, custom CA, granular grants) target larger, regulated deployments.
◆ Prediction
Expect continued engine performance work and Parquet/tiering investment, with capital markets remaining the lead vertical in both features and go-to-market storytelling.
Rivet
6.3DEVOPS
Rivet is rebuilding its actor backend into managed infrastructure for AI agents.
◆ Current state
Rivet ships an actor-model backend - durable per-actor state, SQLite, queues - and is now stacking AI-agent infrastructure on top of it: agentOS (WASM micro-VMs for running coding agents), Secure Exec (isolated process execution), and SDKs in Rust and Effect. The pace is unusual: five 'Introducing' releases in ten days. The core is being rewritten in Rust as it goes.
◆ Where it's heading
The center of gravity is moving from a framework for stateful actors toward a managed platform for hosting agents and their compute. Rivet Compute adds one-command serverless hosting; agentOS and Secure Exec target the sandbox-for-coding-agents market directly. Each release widens the surface a developer can run without managing infrastructure.
◆ Prediction
Expect Rivet to keep filling out the managed-hosting story around Compute - pricing, regions, and tighter agentOS/Secure Exec integration so the actor model and the agent sandbox share one deploy path.
