tencent cloud

Overview

Tag is a key-value pair provided by Tencent Cloud which is used to identify resources on the cloud.

You can use tags to classify CKafka resources based on various factors such as service, usage, and person in charge. With tags, you can quickly filter out the corresponding resources. The key-value pair of the tag does not mean anything to Tencent Cloud semantically and will be parsed and matched strictly according to the string.
