Capabilities

Kat specializes in the following areas:

Kafka Cluster Management

Design, deploy, and manage Kafka clusters with proper partitioning, replication, and high availability. Handle cluster sizing, upgrades, and performance tuning.

Event Streaming Architecture

Build event-driven architectures using Kafka for real-time data processing, event sourcing, CQRS patterns, and microservices communication.

Stream Processing

Implement stream processing applications using Kafka Streams, ksqlDB, and Apache Flink for real-time data transformation and analytics.

Kafka Connect & Integration

Develop and configure Kafka Connect connectors for integrating Kafka with databases, data warehouses, cloud services, and legacy systems.

Schema Management

Implement schema registry, schema evolution, and data serialization using Avro, Protobuf, and JSON Schema for reliable data contracts.

Monitoring & Performance

Monitor Kafka clusters with metrics, alerts, and dashboards. Optimize throughput, latency, and resource utilization for high-performance streaming.

  agentId: 'kat',
  task: 'Build event streaming platform for real-time analytics',
  context: {
    requirements: [
      'Ingest 100K events/sec from 50+ sources',
      'Real-time stream processing',
      'Event replay capability',
      'Schema evolution support',
      'Multi-datacenter replication',
    ],
    sources: ['Web apps', 'Mobile apps', 'IoT devices', 'Databases', 'Third-party APIs'],
    consumers: ['Analytics dashboard', 'ML models', 'Data warehouse', 'Alerting system'],
    infrastructure: 'Kubernetes',
    schemaManagement: 'Avro + Schema Registry',
  },
  deliverables: ['kafka-cluster', 'stream-processors', 'connectors', 'monitoring', 'documentation'],
})

Stream Processing Pipeline

Have Kat implement real-time stream processing applications.

const task = await $.Agent.invoke({
  agentId: 'kat',
  task: 'Build real-time fraud detection stream processor',
  context: {
    input: 'Payment transaction events (50K/sec)',
    processing: [
      'Real-time transaction validation',
      'Pattern matching for fraud detection',
      'Risk scoring with ML model',
      'Aggregate analytics (windowing)',
      'Alert generation for high-risk transactions',
    ],
    output: ['Fraud alerts', 'Risk scores', 'Analytics metrics'],
    technology: 'Kafka Streams + ksqlDB',
    latency: '<100ms P99',
    reliability: 'Exactly-once processing',
  },
  deliverables: ['stream-processor', 'fraud-detection-logic', 'monitoring', 'tests'],
})

Kafka Performance Optimization

Request Kat to optimize Kafka cluster performance.

const task = await $.Agent.invoke({
  agentId: 'kat',
  task: 'Optimize Kafka cluster performance and reliability',
  context: {
    cluster: '12 brokers, 500 topics, 5K partitions',
    issues: ['High latency during peak (500ms P99)', 'Consumer lag increasing', 'Uneven partition distribution', 'Frequent rebalancing'],
    traffic: '200K msg/sec peak, 2TB/day',
    requirements: ['Reduce latency to <50ms P99', 'Eliminate consumer lag', 'Balance partition load', 'Minimize rebalancing impact'],
  },
  deliverables: ['optimization-plan', 'configuration-changes', 'performance-tests', 'monitoring-updates'],
})
