Distributed indexed KNN system

  • Move CF-topology to module
  • Content-based recommendation
    • Select closest data centre
    • Add item to bounded ring
    • Delete item from bounded ring
    • Merge bounded ring to its partner
    • Split bounded ring into 2
  • Learn / GET KNN query
    • RequestForRecommendation should contain correlation ID in order to send result back to client
    • Set different consumer group from CF topo
    • Spout consume from RequestForRecommendation topic
    • Layer 1. Input: K = limit, a*b >= K, b <= MIN_CAPACITY. Output: [R1,R2,....Ra]
    • Layer 2. Run BNN algorithm on individual bounded ring
    • Layer 3. Hold thread until all bounded ring complete BNN and compute Kth value from them
    • Will ever layer1 be slower than layer 2 + 3 ????
  • Synchronous req/res pattern leverage Kafka broker
