Kafka Connect currently supports two execution modes: standalone and distributed.
Starting Connect in Standalone Mode
Start Connect in standalone mode by running the following command:
bin/connect-standalone.sh config/connect-standalone.properties connector1.properties [connector2.properties ...]
Accessing CKafka is basically the same as accessing the open-source Kafka, except that you need to change the value of bootstrap.servers
to the IP address assigned when you apply for the instance.
Starting Connect in Distributed Mode
Start Connect in distributed mode by running the following command:
bin/connect-distributed.sh config/connect-distributed.properties
In this mode, Kafka Connect stores the offset, configuration, and task status information in Kafka topics, which are configured in the following fields in connect-distributed
:
config.storage.topic
offset.storage.topic
status.storage.topic
These topics need to be created manually to ensure that their attributes meet the requirements of Connect.
config.storage.topic
should have only one partition and multiple replicas and be in compact mode.
offset.storage.topic
should have multiple partitions and replicas and be in compact mode.
status.storage.topic
should have multiple partitions and replicas and be in compact mode.
Set bootstrap.servers
to the IP address assigned when you apply for the instance.
Configure group.id
to identify the Connect cluster, which should be differentiated from the consumer group.
