This feature is crucial for scenarios where message sequence is essential for correct processing or maintaining data integrity, such as processing financial transactions, maintaining stateful workflows, or ensuring consistency in event-driven systems.<\/p>\r\n<p>To enable message ordering in Pub\/Sub subscriptions, users need to set the attribute <code>enableMessageOrdering<\/code> to <code>true<\/code> when creating or updating the subscription. When message ordering is enabled, Pub\/Sub guarantees that messages with the same ordering key are delivered to subscribers in the order they were published, preserving the message sequence.<\/p>\r\n<p>It&#8217;s important to note that enabling message ordering can impact system performance and throughput, as Pub\/Sub may need to serialize message delivery to ensure order preservation. Therefore, users should carefully consider the trade-offs between message ordering and system scalability when designing their Pub\/Sub subscriptions.<\/p>\r\n<p>Additionally, users should ensure that their message processing logic can handle potential delays or latencies introduced by message ordering, especially in high-throughput or latency-sensitive applications.<\/p>\r\n<h3><strong>Prerequisites<\/strong><\/h3>\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-9392\" src=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-646.png\" alt=\"\" srcset=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-646.png 628w, https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/image-646-300x66.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-9393\" src=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-4.jpg\" alt=\"\" srcset=\"https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-4.jpg 649w, https:\/\/prwatech.in\/blog\/wp-content\/uploads\/2021\/05\/2-4-300x190.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.
