Can this skill help with ksqlDB performance tuning?

Yes, it provides best practices for partition alignment, using materialized views for pre-computation, and filtering data early in the pipeline to reduce processing overhead.

How do I handle late-arriving events in ksqlDB?

You can use the GRACE PERIOD clause within your windowing logic to allow a specific time buffer for late events to be included in aggregations before the window closes.

What are the benefits of using Materialized Views?

Materialized views pre-compute aggregates in real-time, allowing for instant 'pull' queries that return results much faster than scanning an entire raw event stream.

Does it support Change Data Capture (CDC)?

Absolutely, the skill includes patterns for ingesting and processing CDC logs from databases using tools like Debezium integrated with ksqlDB.

What is the difference between a Stream and a Table in ksqlDB?

A Stream is an immutable, append-only sequence of events representing every change, while a Table represents the current state or the latest value for a given key.
