Overview

SPQR Infra mode is a special deployment where each spqr-router instance acts as both a router and a coordinator in a single binary. This mode is ideal when you want to save CPU and memory resources or simplify your deployment architecture. In SPQR Infra mode:
  • A single spqr-router binary provides both routing and coordination functions
  • Multiple instances form a distributed consensus group
  • An etcd cluster is required for distributed state
  • You should run an odd number of instances (1, 3, or 5)
  • Reduced operational overhead compared to separate router and coordinator deployments

Setup

​
1. Deploy etcd Cluster

Set up an etcd cluster to serve as the QDB. For production, we recommend using a 3-node cluster. Example: Single-node etcd (for testing) 
etcd --listen-client-urls http://0.0.0.0:2379 \
     --advertise-client-urls http://localhost:2379
For production, follow the etcd clustering guide. 🚧 This section is under construction
