Materialize Features


Write SQL Queries. Stream your data.

No manually glueing streams. No writing imperative code.

Declare what you want in SQL. Materialize keeps it up to date. Within milliseconds.

ANSI Standard SQL. Including joins.

No "inspired by SQL" half-broken query languages. Materialize supports ANSI Standard SQL 92. Use a SQL shell or your favorite database adapter.

Correct answers

No page long caveats about eventual consistency and out-of-order execution. Materialize results are always consistent and always up-to-date. Pretend that we reran every query every message.

Distributed. Fault-tolerant. Replicated.

Materialize is built on top of Timely Dataflow, which is distributed. Materialize also adds active-active cluster replication for fault-tolerance, and autoscaling orchestration.

Scales up... and down.

Scale up: process millions of messages per second on a single-digit number of machines. Scale down: run Materialize on your laptop with a single binary on a single core. Either way, it's likely faster than the competition.

Powered by Timely Dataflow

Materialize is built on top of a powerful stream processing engine: Timely Dataflow. Inspired by the award-winning Naiad project, Timely Dataflow has been in open-source development for 4 years and runs in production deployments at scale.
