Set up the Tansu broker using SQLite on an AWS t3.micro instance, taking advantage of the AWS Free Tier. The guide covers installation, configuration, and performance testing, demonstrating how to launch a low-cost Kafka-compatible broker for early-stage projects.
- Tansu with embedded SQLite runs a full Kafka-compatible broker on a free t3.micro (1GiB RAM), storing everything in a single tansu.db file for trivial backup/restore.
- Despite minimal hardware (~10MB/s EBS baseline throughput), the setup delivers usable, measurable throughput and latency, proving Kafka-compatible workloads are feasible on free-tier resources.
- Running below the t3 baseline CPU utilization accumulates burst credits, letting the broker handle demand spikes without extra cost.
- Tansu itself is lightweight on memory, leaving most of the 1GiB instance free for other system needs.
