A tag is a key-value pair provided by Tencent Cloud to identify a resource in the cloud. You can use tags to easily categorize and manage TDMQ for Pulsar resources in many dimensions such as business, purpose, and owner.
Note
Tencent Cloud will not use the tags you set, and they will only be used for your management of TDMQ for Pulsar resources.
Use limits
The use limits of tags are as follows:
Limit Type
Description
Quantity
Each Tencent Cloud resource can have up to 50 tags.
Tag key
Do not create tag keys prefixed with qcloud, tencent, or project because they are reserved for the system.
A tag key can contain up to 255 digits, letters, and symbols +=.@-.
Tag value
It can be either an empty string or a string of up to 127 digits, letters, and symbols +=.@-.
