Setup Environment for Smart Buffering

Before building the smart buffering system, configure your environment variables.

Prerequisites​

Ensure you have completed the Local Development Setup guide.

Step 1: Configure Environment Variables​

# Set destination endpoint
export DESTINATION_URL="http://localhost:9000/events"

# Optional: fallback endpoint for overflow
export FALLBACK_URL="http://localhost:9001/events"

# Set edge node identifier for tracking
export NODE_ID="edge-node-01"

# Verify environment variables
echo "Destination: $DESTINATION_URL"
echo "Fallback: $FALLBACK_URL"
echo "Node ID: $NODE_ID"

Step 2: Start a Test Receiver (Optional)​

For testing, start a simple HTTP server to receive events:

# Using Python (in a separate terminal)
python3 -m http.server 9000

# Or using netcat to see raw requests
nc -l 9000

Next Steps​

With your environment configured, you're ready to implement smart buffering:

What's Next​

  • Step 1: Classify messages into priority tiers (important, regular, archive)
  • Step 2: Add numeric priority scores for fine-grained ordering
  • Step 3: Configure buffer to sort by priority before delivery
  • Step 4: Add age-based escalation to prevent message starvation
