A tag is an identifier of a stream. Adding tags to streams can help you identify and manage your stream resources.

You can add a maximum of 10 tags to a stream when creating the stream or add them on the details page of the created stream.

A tag consists of a tag key and a tag value. Table 1 describes the rules for naming the tag key and value.

**Table 1** Naming rules for a tag key and value

Key	A tag key cannot be left blank. A stream can have only one tag key. You can enter a maximum of 36 characters for Key. The value of Key cannot start or end with a space and cannot contain any of the following characters: is equal to (=), asterisk (*), is less than (<), is greater than (>), backslash (\), comma (,), delimiter (\|), and slash (/).
