Symptoms

When you view the consumption status of a group, the Consumer Offset value is not equal to the Maximum Offset value, but the Accumulated Messages value is 0 or empty.

Causes

  • You have not submitted a consumer offset, or the consumer offset that you submitted has expired.
  • You have submitted a consumer offset and the consumer offset is in effect, but some messages are deleted due to expiration, which causes the displayed consumer offset to be smaller than or equal to the minimum offset.
