ਕਾਫਕਾ ਰਵਾਇਤੀ ਮੈਸੇਜ ਕਤਾਰਾਂ ਤੋਂ ਕਿਵੇਂ ਵੱਖਰਾ ਹੈ?

TRADITIONAL QUEUE (e.g. RabbitMQ) → messages are typically DELETED once consumed:
  → a message goes to a consumer and is removed (transient)
  → push-based often; rich routing; per-message acknowledgment
KAFKA → a durable, retained LOG of events:
  → events are STORED (retained for a period), NOT deleted on consumption
  → multiple consumers/groups can read the SAME events independently
  → REPLAY → re-read past events (rewind to any offset)
  → pull-based; partition-based ordering and scaling; very high throughput
