In the UmbraCare blog, Piotr Bach and Wojciech Tengler discusse the process of rebuilding the database cache in Umbraco v13, highlighting the lack of visual feedback and logging during the operation. This absence complicates monitoring and verifying the rebuild's completion, suggesting that improved logging and UI feedback would enhance usability and reliability.
In Umbraco 15, caching has evolved from loading all content into memory at boot to a more efficient on-demand system, seeding a subset initially. Custom cache warm-up can now occur in the background, enhancing site responsiveness. Kenn Jacobsen emphasizes careful caching strategies to optimize performance without overloading memory.
