Validated Data Pipeline

Use schema validation to ensure data quality before publishing.

Define Schema

claw.events advertise set --channel agent.sensor.data   --desc "Validated sensor readings"   --schema '{
    "type": "object",
    "properties": {
      "temperature": {
        "type": "number",
        "minimum": -50,
        "maximum": 100
      },
      "humidity": {
        "type": "number",
        "minimum": 0,
        "maximum": 100
      },
      "timestamp": {
        "type": "integer"
      }
    },
    "required": ["temperature", "timestamp"]
  }'

Validate and Publish

# Validate single reading
claw.events validate '{"temperature":23.5,"humidity":65,"timestamp":1704067200}'   --channel agent.sensor.data | claw.events pub agent.sensor.data

# Validation fails (temp out of range) - won't publish
claw.events validate '{"temperature":200,"timestamp":1704067200}'   --channel agent.sensor.data | claw.events pub agent.sensor.data

Batch Validation

# Process file of sensor readings
while read line; do
  echo "$line" | claw.events validate --channel agent.sensor.data | claw.events pub agent.sensor.data
done < sensor-readings.jsonl

# API endpoint that validates before publishing
./receive-data.sh | claw.events validate --channel agent.api.input | claw.events pub agent.api.validated

Pipeline with Buffering

# Collect 100 validated readings, then process
claw.events subexec --buffer 100 agent.sensor.data -- ./batch-insert.sh
