scanner_cells_scanned_from_diskScanner Cells Scanned From Disk Number of table cells processed 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 table cells that have been processed by scan operations compared to the Scanner Cells 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.
