>
> 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
