Stream Processing Guarantee

A Stream Processing Guarantee is a distributed system guarantee that defines stream processing delivery semantics for stream processing events in stream processing systems under stream processing failure scenarios.

• Context:
  • It can typically ensure Stream Processing Event Delivery through stream processing acknowledgment mechanisms.
  • It can typically handle Stream Processing Failure Recovery through stream processing checkpoints.
  • It can typically trade-off Stream Processing Performance against stream processing correctness.
  • It can typically maintain Stream Processing State Consistency through stream processing transaction logs.
  • It can typically support Stream Processing Deduplication through stream processing idempotency.
  • ...
  • It can often coordinate Stream Processing Distributed Transactions through stream processing two-phase commits.
  • It can often provide Stream Processing Progress Tracking through stream processing offset management.
  • It can often enable Stream Processing Replay through stream processing event retention.
  • It can often optimize Stream Processing Throughput based on stream processing guarantee levels.
  • ...
  • It can range from being a Weak Stream Processing Guarantee to being a Strong Stream Processing Guarantee, depending on its stream processing consistency level.
  • It can range from being a Best-Effort Stream Processing Guarantee to being a Transactional Stream Processing Guarantee, depending on its stream processing reliability requirements.
  • ...
  • It can coordinate with Stream Processing State Management for stream processing fault tolerance.
  • It can integrate with Stream Processing Checkpoint Coordinators for stream processing recovery points.
  • It can interface with Stream Processing Source Systems for stream processing replay capability.
  • It can communicate with Stream Processing Sink Systems for stream processing delivery confirmation.
  • ...
• Example(s):
  • Stream Processing Delivery Semantics, such as:
    • At-Most-Once Stream Processing Guarantee for stream processing fire-and-forget delivery.
    • At-Least-Once Stream Processing Guarantee for stream processing reliable delivery.
    • Exactly-Once Stream Processing Guarantee for stream processing transactional delivery.
  • Stream Processing Guarantee Implementations, such as:
    • Kafka Streams Stream Processing Guarantee for stream processing Kafka-based system.
    • Apache Flink Stream Processing Guarantee for stream processing stateful computation.
    • Apache Spark Structured Streaming Processing Guarantee for stream processing micro-batch system.
  • Stream Processing Guarantee Levels, such as:
    • End-to-End Stream Processing Guarantee for stream processing complete pipeline.
    • Internal Stream Processing Guarantee for stream processing framework boundary.
  • ...
• Counter-Example(s):
  • Database ACID Guarantee, which ensures transaction propertys rather than stream processing delivery.
  • Network Protocol Guarantee, which handles packet delivery rather than stream processing event semantics.
  • Service Level Agreement, which defines operational metrics rather than stream processing correctness.
