Gatsby Cloud has introduced Incremental Deploys as a default for all builds, significantly enhancing the content publishing process with Reactive Site Generation (RSG). This feature allows for incremental content publishing, improving upon the previously implemented Incremental Builds in Gatsby 3, by optimizing the entire workflow from queue time to deploy time. The queue time has been reduced from over 10 seconds to 2 seconds, while the build time for large sites has decreased from over 5 minutes to less than 10 seconds. The new Incremental Deploys feature further reduces the median build and deploy time to 3 seconds, achieving a tenfold improvement. Consequently, the overall time to live for content changes on static websites has been significantly shortened to a median of 5 seconds, offering content editors a more efficient publishing experience. Webstacks, Gatsby's agency of the year in 2021, highlighted the performance enhancements, noting a 30-50% faster publishing time for enterprise sites.
