Update config.example.yaml with: - Recommendations for very large deployments (30+ nodes) - Formula for calculating optimal rate limits based on node count - Example calculation: 30 nodes with 10s polling = 300ms interval - Security note about minimum safe intervals This helps admins properly configure the proxy for enterprise deployments with dozens of nodes.

# Rate Limiting (Optional)
|
|
# Control how frequently peers can make requests to prevent abuse
|
|
# Adjust these values based on your deployment size:
|
|
# - Small (1-3 nodes): Use defaults (1000ms, burst 5)
|
|
# - Medium (4-10 nodes): 500ms, burst 10
|
|
# - Large (10-20 nodes): 250ms, burst 20
|
|
# - Very Large (30+ nodes): 100ms, burst 30-50
|
|
#
|
|
# Formula: To poll all nodes in one cycle, set burst >= node_count
|
|
# For optimal performance: per_peer_interval_ms = (polling_interval_ms / node_count)
|
|
# Example: 10 second polling with 30 nodes = 10000ms / 30 ≈ 300ms interval
|
|
rate_limit:
|
|
per_peer_interval_ms: 1000 # Minimum milliseconds between requests per peer (1000ms = 1 qps = 60 requests/min)
|
|
per_peer_burst: 5 # Number of requests allowed in a burst (supports up to 5 simultaneous requests)
|
|
|
|
# Default values if not specified:
|
|
# per_peer_interval_ms: 1000 (1 second = 1 qps = 60 requests/min)
|
|
# per_peer_burst: 5
|
|
#
|
|
# Security note: Lower intervals increase throughput but also increase exposure
|
|
# to potential abuse. For production, keep interval >= 100ms unless necessary.
