It enables efficient, real-time ingestion, processing, and monitoring of petabytes of data per day, generated by billions of sensors and data collectors. With its built-in caching, stream processing, and data subscription capabilities, TDengine offers a simplified solution for time-series data processing.<\/p>\n\n\n\n<h2 class=\"gb-headline gb-headline-b6ecb6c3 gb-headline-text\">What&#8217;s New<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The <code class=\"\" data-line=\"\">INTERP()<\/code> function has been improved:<\/strong> You can now specify a constant expression for the <code class=\"\" data-line=\"\">FILL<\/code> clause. You can also interpolate a single data point by specifying a single time value in the <code class=\"\" data-line=\"\">RANGE<\/code> clause.<\/li>\n\n\n\n<li><strong>A time-to-live (TTL) value can be set for tables and subtables:<\/strong> You can specify a date after which a table or subtable will be deleted automatically. This date can be updated dynamically when actions occur on a table or set as a static value.<\/li>\n\n\n\n<li><strong>(Enterprise Edition only) Virtual node groups can be split:<\/strong> You can use the <code class=\"\" data-line=\"\">SPLIT VGROUP<\/code> command to split virtual node groups in a three-node cluster for load balancing purposes.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"gb-headline gb-headline-e48f4d8f gb-headline-text\">Compatibility<\/h2>\n\n\n\n<p>You can run TDengine 3.0.6.0 on Linux, macOS, and Windows, in addition to Docker containers and Kubernetes. See <a href=\"https:\/\/docs.tdengine.com\/tdengine-reference\/supported-platforms\/\">Supported Platforms<\/a> for details about the compatibility of TDengine 3.0.6.0 with various architectures and operating systems.<\/p>\n\n\n\n<p><strong>Note:<\/strong> You must upgrade existing clients to TDengine 3.0.6.0 before connecting to a TDengine 3.0.6.0 server.<\/p>\n\n\n\n<h2 class=\"gb-headline gb-headline-d46ee0ec gb-headline-text\">Upgrading to TDengine 3.0.6.0<\/h2>\n\n\n\n<h3 class=\"gb-headline gb-headline-59bc1217 gb-headline-text\">Upgrading TDengine Cloud<\/h3>\n\n\n\n<p>TDengine Cloud instances will be upgraded automatically, and an account representative will notify you of the next scheduled maintenance window during which your instances will be upgraded. Note that if you manually shut down your instances prior to the maintenance window, those instances will be automatically upgraded to the latest version.<\/p>\n\n\n\n<p>Any TDengine Cloud instances on the legacy Free Plan are automatically upgraded the next time they are shut down. You can manually shut down an instance by opening the <strong>Instances<\/strong> tab and clicking the <strong>Active<\/strong> slider.<\/p>\n\n\n\n<p>You can check your current version of TDengine at any time by running the <code class=\"\" data-line=\"\">SELECT SERVER_VERSION();<\/code> command.<\/p>\n\n\n\n<h3 class=\"gb-headline gb-headline-a8c557d0 gb-headline-text\">Upgrading TDengine Community and Enterprise Editions<\/h3>\n\n\n\n<p>You can upgrade TDengine Community Edition and TDengine Enterprise Edition to version 3.0.6.0 from version 3.0.1.5 or later.<\/p>\n\n\n\n<p>To upgrade TDengine Community Edition or TDengine Enterprise Edition, first back up your deployment by making a copy of the TDengine directory. Then install TDengine 3.0.6.0 as described in the <a href=\"https:\/\/docs.tdengine.com\/get-started\/\">official documentation<\/a>. It is not necessary to uninstall TDengine before upgrading.<\/p>\n\n\n\n<p><strong>Note:<\/strong> If you have deployed TDengine as a cluster, you must shut down and upgrade all nodes in the cluster to TDengine 3.0.6.0. Rolling upgrades are not supported in TDengine 3.0.6.0.<\/p>\n\n\n\n<p>If you are running TDengine 2.6 or earlier, contact the TDengine Team for assistance in migrating your deployment to TDengine 3.0.6.0. TDengine Enterprise Edition customers can contact their account representative for support, and all users can join the <a href=\"https:\/\/discord.com\/invite\/VZdSuUg4pS\" rel=\"noopener\">TDengine Discord<\/a> server and request help from the team.<\/p>\n\n\n\n<h2 class=\"gb-headline gb-headline-3c4c8a0e gb-headline-text\">Resolved Issues<\/h2>\n\n\n\n<p>For a full list of issues resolved in this release, see <a href=\"https:\/\/github.com\/taosdata\/TDengine\/releases\/tag\/ver-3.0.6.0\" rel=\"noopener\">our GitHub repository<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This document contains the release notes for TDengine 3.0.6.0.<\/p>\n","protected":false},"author":102,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"content-type":"","footnotes":""},"categories":[22],"tags":[],"ppma_author":[181],"class_list":["post-14161","post","type-post","status-publish","format-standard","hentry","category-news"],"authors":[{"term_id":181,"user_id":102,"is_guest":0,"slug":"tdengine-team","display_name":"TDengine Team","avatar_url":{"url":"https:\/\/tdengine.com\/wp-content\/uploads\/29.03-01-tdengine.png","url2x":"https:\/\/tdengine.com\/wp-content\/uploads\/29.03-01-tdengine.png"},"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/posts\/14161","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/users\/102"}],"replies":[{"embeddable":true,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/comments?post=14161"}],"version-history":[{"count":10,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/posts\/14161\/revisions"}],"predecessor-version":[{"id":24680,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/posts\/14161\/revisions\/24680"}],"wp:attachment":[{"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/media?parent=14161"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/categories?post=14161"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/tags?post=14161"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/tdengine.com\/wp-json\/wp\/v2\/ppma_author?post=14161"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
