Stream Processing Window

A Stream Processing Window is a temporal boundary mechanism that groups stream processing events within stream processing time intervals for stream processing aggregation operations.

• Context:
  • It can typically aggregate Stream Processing Events using stream processing window functions.
  • It can typically trigger Stream Processing Computations based on stream processing window completion.
  • It can typically handle Stream Processing Late Events through stream processing window allowances.
  • It can typically maintain Stream Processing Window State across stream processing partitions.
  • It can typically support Stream Processing Window Merges for stream processing session windows.
  • ...
  • It can often optimize Stream Processing Window Memory through stream processing incremental aggregation.
  • It can often provide Stream Processing Window Watermarks for stream processing progress tracking.
  • It can often enable Stream Processing Window Early Results through stream processing trigger policy.
  • It can often handle Stream Processing Window Out-of-Order Events through stream processing buffering.
  • ...
  • It can range from being a Fixed Stream Processing Window to being a Dynamic Stream Processing Window, depending on its stream processing window flexibility.
  • It can range from being a Small Stream Processing Window to being a Large Stream Processing Window, depending on its stream processing window duration.
  • ...
  • It can coordinate with Stream Processing Watermarks for stream processing progress tracking.
  • It can integrate with Stream Processing State Backends for stream processing window storage.
  • It can interface with Stream Processing Timer Services for stream processing window triggering.
  • It can communicate with Stream Processing Checkpoints for stream processing window recovery.
  • ...
• Example(s):
  • Stream Processing Time Windows, such as:
    • Tumbling Stream Processing Window for stream processing non-overlapping window.
    • Sliding Stream Processing Window for stream processing overlapping window.
    • Session Stream Processing Window for stream processing activity-based window.
  • Stream Processing Count Windows, such as:
    • Fixed-Count Stream Processing Window for stream processing element-based window.
    • Sliding-Count Stream Processing Window for stream processing overlapping count window.
  • Stream Processing Custom Windows, such as:
    • Global Stream Processing Window for stream processing unbounded window.
    • Calendar Stream Processing Window for stream processing natural time boundary.
  • ...
• Counter-Example(s):
  • Database View, which provides static aggregation rather than stream processing window operations.
  • Batch Processing Partition, which divides data batches rather than stream processing event flows.
  • Cache Window, which manages memory allocation rather than stream processing temporal boundarys.
