-----------------------------------
Summary: Metadata API ignores topic names if at least one topic is
provided with an id
Key: KAFKA-14764
URL: https://issues.apache.org/jira/browse/KAFKA-14764
Project: Kafka
Issue Type: Bug
Reporter: David Jacot
The Metadata API accepts both topic names and topic ids in the request. This
suggests that a single request could mix them in. At least, we have no logic on
the server side to prevent this. The issue is that the server just ignores any
topic specified with a name if there is at least one topic specified with an id
in the request. In other words, if a request contains topic-id-1, topic-id-2,
topic-name-1 and topic-name-2, the response will only have metadata for
topic-id-1 and topic-id-2.
This does not hurt us today because the clients does not use topic ids in the
request at all.
