Yury Gerzhedovich updated IGNITE-8580: -------------------------------------- Summary: Expose interface for IO metrics (was: Expose interface for IO metrics spitted by type) > Expose interface for IO metrics > ------------------------------- > > Key: IGNITE-8580 > URL: https://issues.apache.org/jira/browse/IGNITE-8580 > Project: Ignite > Issue Type: Task > Components: persistence, sql > Reporter: Vladimir Ozerov > Assignee: Yury Gerzhedovich > Priority: Major > Labels: iep-27 > Fix For: 2.8 > > > 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 > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
