It enables real-time ingestion, storage, analysis, and distribution of petabytes of data per day, generated by billions of sensors and data collectors. With TDengine making big data accessible, valuable, and affordable, digital transformation has never been easier.<\/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>Integration with Apache Superset:<\/strong> You can now use data stored in TDengine with Apache Superset, a modern data exploration and visualization platform.
