Yury Gerzhedovich updated IGNITE-8580:
--------------------------------------
Description:
Currently it is impossible to track how many pages of a certain type were read
from or written to disk. This might be very useful for performance tuning and
debugging purposes. E.g. excessive page reads may highlight missing SQL index.
We need to expose total physical read/write, logical read pages metrics
splitted by types (see
org.apache.ignite.internal.processors.cache.persistence.tree.io.PageIO#getType()).
Also need to expose IO statistics by aggregate page type like DATA, INDEX,
OTHER
