Lambda architecture combines batch and real-time processing:

• Pros: Processes both historical and real-time data.
• Cons: Requires maintaining two separate systems, increasing complexity.

Kappa architecture simplifies this by using a single stream-processing layer: 

• Pros: Processes all data in real time, ensuring efficiency. 
• Cons: May not support certain legacy batch workflows as easily as Lambda

Snowplow’s event pipeline and trackers support both architectures, giving you flexibility in building real-time batch systems.
