> 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 read/write pages metrics splitted by page type (see org.apache.ignite.internal.processors.cache.persistence.tree.io.PageIO#getType()).
