# WarpStream

> Diskless Kafka-compatible streaming straight to object storage

WarpStream is a Kafka-compatible streaming platform with no local disks, writing directly to S3-class object storage, and running its stateless agents inside the customer's own cloud account under a bring-your-own-cloud model.

## Use it when

- The Kafka bill is dominated by replicated disks and cross-zone traffic; writing straight to object storage removes both.
- Data must never leave your account: stateless agents run in your VPC, WarpStream operates only the control plane, and topic contents stay unreadable to the vendor.
- Elasticity should be trivial; agents are stateless, so scaling adds or removes processes and nothing rebalances.
- The workload is logs, telemetry, or analytics feeds, where seconds of latency are irrelevant.

## Think twice when

- Latency is part of the product; batching into object storage adds end-to-end delay a local-disk Kafka cluster does not have.
- You want open source or self-contained self-hosting; WarpStream is proprietary and its control plane is the vendor's (AutoMQ is the Apache-2.0 alternative on the same architecture).
- Full Kafka protocol coverage is assumed; some broker requests are unsupported.

## How it runs

Bring-your-own-cloud: deploy stateless agents in your VPC against your S3, GCS, or Azure storage; WarpStream Cloud tracks file-to-partition mapping, compaction, and retention. Managed Data Pipelines run Bento connectors inside the agents. Billing is uncompressed GiB written and stored plus cluster-minutes, with no availability-zone fees.
