Which statement describes the storage location for a sink connector’s offsets?
A.
The __consumer_offsets topic, like any other consumer
B.
The topic specified in the offsets.storage.topic configuration parameter
C.
In a file specified by the offset.storage.file.filename configuration parameter
D.
In memory which is then periodically flushed to a RocksDB instance
The Answer Is:
A
This question includes an explanation.
Explanation:
Kafka Connect sink connectors use the standard Kafka consumer mechanism to track offsets, which means offsets are stored in the __consumer_offsets internal topic.
From Kafka Connect Documentation:
“Sink connectors are regular Kafka consumers and store their offsets in the __consumer_offsets topic like any other consumer.”
The other options refer to source connectors or worker configuration.
offsets.storage.topic is relevant for source connectors.
