Mark Cache

These metrics include the total size of the mark cache as well as the number of cache hits and misses. They are useful for understanding query performance and for managing cache efficiency within your cluster. 

• Mark Cache: bytes – Total size of mark cache in bytes.
• Mark Cache Hits – Number of times an entry has been found in the mark cache, so we didn’t have to load a mark file.
• Mark Cache Misses – Number of times an entry has not been found in the mark cache, so we had to load a mark file in memory, which is a costly operation, adding to query latency.
