Explanation

Pipeline caching can help reduce build time by allowing the outputs or downloaded dependencies from one run to be reused in later runs, thereby reducing or avoiding the cost to recreate or redownload the same files again. Caching is especially useful in scenarios where the same dependencies are downloaded over and over at the start of each run. This is often a time consuming process involving hundreds or thousands of network calls. Caching can be effective at improving build time provided the time to restore and save the cache is less than the time to produce the output again from scratch. Because of this, caching may not be effective in all scenarios and may actually have a negative impact on build time. https://docs.microsoft.com/en-us/azure/devops/pipelines/release/caching?view=azure-devops
