Buffer (data)
A temporary storage area that holds data while it waits to be processed. Buffers prevent data loss during traffic spikes when 500 form submissions arrive simultaneously, the buffer queues them for orderly processing.
Expert insight
A buffer that queues events for batch processing trades latency for efficiency, events wait in the buffer until either a size threshold or a time threshold is hit. Setting both thresholds too high delays processing unnecessarily; setting them too low defeats the purpose of batching in the first place, the right values depend on how time-sensitive the downstream action actually is.
In a real workflow
Webhooks are written to a buffer table first, then processed in order, so a spike never loses events.
Common mistakes
- Never emptying the buffer.
- Not monitoring how far behind processing is.
Complexity level
Requires some familiarity with automation concepts.
