["Pavel Tupitsyn (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-6030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16196610#comment-16196610 ] 

Pavel Tupitsyn commented on IGNITE-6030:
----------------------------------------

{code}
DefaultRegionConfiguration
DataRegions
{code}

Looks inconsistent to me. In one case we call it RegionConfiguration, in another case DataRegion.
