scanner_bytes_scanned_from_diskScanner Bytes Scanned From Disk Number of bytes read by scan requests. This is measured as a raw count prior to application of predicates, deleted data,or MVCC-based filtering. Thus, this is a better measure of actual IO that has been caused by scan operations compared to the Scanner Bytes Returned metric. Note that this only counts data that has been flushed to disk, and does not include data read from in-memory stores. However, itincludes both cache misses and cache hits.
