Ready to deploy? Here is a minimal implementation using the Python API. KeyMaker-DVT

Step 1: Installation

pip install keymaker-dvt
docker pull keymaker/dvt-stream-processor:latest

Step 2: Define a Validation Contract (YAML)

# contract/user_orders.yaml
dataset: "clickstream.events"
keys:
  - composite: ["user_id", "session_id"]
  - time_bucket: "15m"
rules:

Step 3: Run the Stream Validator
from keymaker_dvt import StreamValidator, KafkaSource
validator = StreamValidator.from_yaml("contract/user_orders.yaml")
source = KafkaSource(topic="raw_orders", bootstrap_servers="localhost:9092")
async for record in source:
result = await validator.validate(record)
if result.is_valid:
await result.write_to_sink("validated_orders")
else:
await result.send_to_dead_letter(exception=result.errors)

Banks use KeyMaker-DVT to validate transaction streams against anti-money laundering (AML) rules. The KeyMaker engine generates a composite key per account/hour, enabling real-time velocity checks without database round-trips. | Issue ID | Severity | Description |
3.1 Hardware Under Test (HUT)

3.2 Environmental Conditions


Acme Corp, a global logistics provider, had a recurring problem: bad address data from 50+ regional ERPs was corrupting their warehouse management system. Manual cleanup cost $180,000 per quarter.
After implementing KeyMaker-DVT with a composite key of (postal_code + street_hash + consignee_id), they reduced address validation errors by 99.7%. Automated quarantine of bad records prevented downstream corruption. In the first year alone, they saved $2.2M in operational write-offs and developer debugging time. Step 2: Define a Validation Contract (YAML) #
Traditional tools create a single bottleneck. KeyMaker-DVT uses a distributed hash table (DHT) to spread validation rules across worker nodes. Each rule (e.g., "total_sales > 0") becomes a validation cell in the matrix. The synthesized key directs the record to the correct cell without a global lock.
