Which of the following is the correct way to define a tumbling window of 10 seconds in Kafka Streams Java API?

easy📝 Syntax Q3 of Q15

Kafka - Streams

ATimeWindows.ofSizeWithNoGrace(Duration.ofSeconds(10))

BTimeWindows.of(Duration.ofSeconds(10)).advanceBy(Duration.ofSeconds(5))

CSessionWindows.with(Duration.ofSeconds(10))

DHoppingWindows.of(Duration.ofSeconds(10)).advanceBy(Duration.ofSeconds(10))

Step-by-Step Solution

Solution:

Step 1: Recall tumbling window syntax
Tumbling windows use TimeWindows.ofSizeWithNoGrace() or TimeWindows.ofSize() with no advanceBy.
Step 2: Check options
TimeWindows.ofSizeWithNoGrace(Duration.ofSeconds(10)) correctly defines a 10-second tumbling window without grace period. TimeWindows.of(Duration.ofSeconds(10)).advanceBy(Duration.ofSeconds(5)) defines hopping window. SessionWindows.with(Duration.ofSeconds(10)) is session window. HoppingWindows.of(Duration.ofSeconds(10)).advanceBy(Duration.ofSeconds(10)) is hopping window with advance equal to size.
Final Answer:
TimeWindows.ofSizeWithNoGrace(Duration.ofSeconds(10)) -> Option A
Quick Check:
Tumbling window syntax = TimeWindows.ofSizeWithNoGrace() [OK]

Quick Trick: Tumbling windows use TimeWindows.ofSizeWithNoGrace() [OK]
