logos-storage-local-harness
A local, 100% bash-based implementation of a Logos Storage harness that can be used to launch a cluster and run experiments against it.
Some features:
Containerless. Compile your binary and you are ready to go. No need to build Docker images or fiddle with container networking. This makes this particularly suitable for quick experimentation: edit the code, compile, launch the cluster.
Monitoring. The harness includes a Grafana/Prometheus setup which runs on containers and can be started with docker compose. The harness will automatically add Logos Storage processes to Prometheus monitoring with proper experiment and node labels.
Primitives. The harness is built as a collection of primitives which allow:
- setting up and tearing down Logos Storage nodes;
- scripting nodes.
It has been designed with experimentation in mind: setting up scenarios in which nodes are started/stopped and execute a concerted set of actions over which we then do measurements. The harness supports concurrent actions and exposes simple future-like synchronization primitives.
