The formation\nof the data processing, analysis and storage modules highly depends on the\nstructure of the data.<\/li><li>Processing\n&#8211; It defines the processing state of the data.

A tag is a key-value pair\nthat you define for a stream. Using tags is a simple yet powerful way to manage\nAWS resources and organize data, including billing data.<\/p>\n\n\n\n<p>You use the Kinesis Data Streams console, AWS CLI, or\nKinesis Data Streams API to complete the following tasks:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Add\ntags to a stream<\/li><li>List\nthe tags for your streams<\/li><li>Remove\ntags from a stream<\/li><\/ul>\n\n\n\n<p>You can use tags to categorize your streams. For\nexample, you can categorize streams by purpose, owner, or environment. Because\nyou define the key and value for each tag, you can create a custom set of\ncategories to meet your specific needs.<\/p>\n\n\n\n<p><strong>Tag Restrictions<\/strong><\/p>\n\n\n\n<p>The following restrictions apply to tags.<\/p>\n\n\n\n<p>Basic restrictions<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The\nmaximum number of tags per resource (stream) is 50.<\/li><li>Tag\nkeys and values are case-sensitive.<\/li><li>You\ncan&#8217;t change or edit tags for a deleted stream.<\/li><\/ul>\n\n\n\n<p>Tag key restrictions<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Each\ntag key must be unique.
