Missing caching layers. With the reliability pillar of the Well-Architected Framework, organizations must ensure they build resilient and available applications. Some principles Microsoft provides to help organizations across this area include: Define and test availability targets such as service level agreements (SLAs) and SLOs.
having to open each table.frm (and in which my test runs, I have purposely read a very high number of tables compared to “Table-open-cache” variable). When running only sysbench, there is a high number of cache hits (~99.98%) and a low number of “misses,” which means the table_cache is big enough for the workload.
Its raison d’être is to cache result rows from a plan subtree, then replay those rows on subsequent iterations if any correlated loop parameters are unchanged.
