Tom Bentley updated KAFKA-5693: ------------------------------- Fix Version/s: 1.1.0 > TopicCreationPolicy and AlterConfigsPolicy overlap > -------------------------------------------------- > > Key: KAFKA-5693 > URL: https://issues.apache.org/jira/browse/KAFKA-5693 > Project: Kafka > Issue Type: Bug > Reporter: Tom Bentley > Priority: Minor > Fix For: 1.1.0 > > > The administrator of a cluster can configure a {{CreateTopicPolicy}}, which > has access to the topic configs as well as other metadata to make its > decision about whether a topic creation is allowed. Thus in theory the > decision could be based on a combination of of the replication factor, and > the topic configs, for example. > Separately there is an AlterConfigPolicy, which only has access to the > configs (and can apply to configurable entities other than just topics). > There are potential issues with this. For example although the > CreateTopicPolicy is checked at creation time, it's not checked for any later > alterations to the topic config. So policies which depend on both the topic > configs and other topic metadata could be worked around by changing the > configs after creation. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
