    [ https://issues.apache.org/jira/browse/IGNITE-19950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17766824#comment-17766824 ] 

Nikolay Izhikov commented on IGNITE-19950:
------------------------------------------

Design decisions we can changed during performance testing:

* Use per thread buffer to write entries: currently - buffer per partition file.
* Use fully non blocking algorithm based on max entry version - like in incremental snapshots.
* User one file for whole dump to use sequential writes - currently, file per partition.
