-Theodolite contains 4 application benchmarks, which are based on typical use cases for stream processing within microservices. For each benchmark, a corresponding workload generator is provided. Currently, this repository provides benchmark implementations for Apache Kafka Streams. Benchmark implementation for Apache Flink are currently under development and can be found in the *apache-flink* branch of this repository. The benchmark sources can be found in [Thedolite benchmarks](benchmarks).
