A simple key value store that I personally use for learning rust and getting comfortable with its learning curve, including concurrency support, borrowing and whatnot. Part of The Sprawl Project.

1. Clone using SSH

$ git clone [email protected]:the-sprawl-project/construct-cache.git

The system now supports synchronous multi-node replication via a central controlplane.

1. Start the Controlplane: This launches the orchestrator and 3 cache instances (ports 9001-9003).

   cargo run --bin controlplane

2. Launch Clients: Open new terminal windows and connect to different nodes to see replication in action:

   # Terminal A
   cargo run --bin construct_cache_client 9001
   
   # Terminal B
   cargo run --bin construct_cache_client 9002

3. Verify Sync: Create a key on port 9001 (c key val) and then read it from port 9002 (g key).

If you prefer running a single isolated instance:

1. Run the server:

   cargo run --bin construct_cache_server

2. Run the client:

   cargo run --bin construct_cache_client

   (Note: Use h for help within the client.)

When developing features, you might want to sync your protobufs to the main spawl-protocol repository as well. This will allow other repositories to use the same protobuf structures when accessing the Construct Cache.

To sync protobufs, do the following:

1. Setup the sprawl-protocol repository through a git clone.
2. Set the SPRAWL_PROTOCOLS_LOCAL_PATH variable in your .rc file (.zshrc for example) to point to the root of the repository
3. Run make sync-protos-local to sync the protobufs from the sprawl-protocol repo to this project.
4. If any changes are made in this repo to the protobuf structures and should be committed to the sprawl-protocol repository, run make push-protos and commit the changes in that repository.

New features coming soon! Check out the issues tab.
