Incremental Synchronization Error: Topic *** not present in metadata after 300000 ms

Scenarios

During an incremental synchronization from Oracle to Kafka, an error is reported, and the log information is as follows: service INCREMENT failed, cause by: Topic *** not present in metadata after 300000 ms

Possible Causes

If the destination Kafka instance is deployed across multiple AZs and an AZ fails, the preceding error may be reported when the Kafka client produces or consumes messages.

Solution

  1. Check and restore the Kafka partitioning.
  2. In the task list, locate the target task and click Reset in the Operation column to submit the task again.
