Hi, First of all read about the WAL:
https://apacheignite.readme.io/docs/write-ahead-log https://cwiki.apache.org/confluence/display/IGNITE/Ignite+Persistent+Store+-+under+the+hood#IgnitePersistentStore-underthehood-WALHistorySize WAL Work maximum used size: walSegmentSize * walSegments = 640Mb (default). It's a size of your default WAL directory. You have big size of the wall archive because it contains all the information about the previous segments. Looks like at the moment it can't be removed safety until next issue will not be fixed: https://issues.apache.org/jira/browse/IGNITE-7912 it should be available in Ignite 2.7. However, you can try to optimize your WAL usage: 1)Disable the wall archive logging: https://apacheignite.readme.io/docs/write-ahead-log#section-disabling-wal-archiving 2)You can try to turn off you WAL LOG during some operations. It will be very useful to do it during the loading of the data. You can turn off/on WAL logging for required cache using: 1)Java code https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/IgniteCluster.html#disableWal-java.lang.String- 2)SQL: ALTER TABLE tablename NOLOGGING - turn off ALTER TABLE tablename LOGGING - turn on BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
