This feature helps streamline message processing and reduce unnecessary overhead by ensuring that subscribers only receive messages relevant to their needs.<\/p>\r\n<p>Pub\/Sub supports message filtering through subscription filtering, which allows users to define subscription filters using subscription policies. These filters can be configured to match messages based on attributes such as message attributes, message data, or message metadata.<\/p>\r\n<p>Users can specify filtering conditions using Pub\/Sub&#8217;s filtering language, which supports logical operators, comparison operators, and regular expressions. For example, users can define filters to only receive messages with specific attributes or values, messages containing certain keywords or patterns in their content, or messages with timestamps within a certain range.<\/p>\r\n<p><strong>Prerequisites<\/strong><\/p>\r\n\r\n\r\n\r\n<p><a href=\"https:\/\/www.prwatech.com\/course\/gcptraining\" target=\"_blank\" rel=\"noreferrer noopener\" data-type=\"URL\" data-id=\"https:\/\/www.prwatech.com\/course\/gcptraining\">GCP<\/a> account<\/p>\r\n\r\n\r\n\r\n<p>Open Console.<\/p>\r\n\r\n\r\n\r\n<p>Open\u00a0 Menu &gt; <a href=\"https:\/\/prwatech.in\/blog\/google-cloud-platform\/gcp-pubsub\/\" target=\"_blank\" rel=\"noreferrer noopener\" data-type=\"URL\" data-id=\"https:\/\/prwatech.in\/blog\/google-cloud-platform\/gcp-pubsub\/\">Pubsub<\/a> &gt; Subscriptions<\/p>\r\n\r\n\r\n\r\n<p>Click on create\u00a0 Subscription<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"628\" height=\"139\" class=\"wp-image-9385\" src=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-644.png\" alt=\"\" srcset=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-644.png 628w, https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-644-300x66.png 300w\" sizes=\"auto, (max-width: 628px) 100vw, 628px\" \/><\/figure>\r\n\r\n\r\n\r\n<p>Give the subscription ID.<\/p>\r\n\r\n\r\n\r\n<p>Choose the pubsub topic.<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"649\" height=\"412\" class=\"wp-image-9386\" src=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-3.jpg\" alt=\"\" srcset=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-3.jpg 649w, https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-3-300x190.jpg 300w\" sizes=\"auto, (max-width: 649px) 100vw, 649px\" \/><\/figure>\r\n\r\n\r\n\r\n<p>the delivery type.<\/p>\r\n\r\n\r\n\r\n<p>Choose the retention period for message.
