Subject [jira] [Commented] (OAK-5030) Copying the versions store is slow and increase the repository size
Date Wed, 02 Nov 2016 08:21:00 GMT

    [ https://issues.apache.org/jira/browse/OAK-5030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15628177#comment-15628177
] 

Michael Dürig commented on OAK-5030:
------------------------------------

Agreed. A better name for {{NodeBuilder#getNodeState()}} would have been {{.buildNodeState()}},
implying that there is actual work being done. The intended usage pattern for {{NodeBuilders}}
actually is acquire, modify, build, throw away. However, unfortunately this is not properly
reflected in its methods and their semantics. 

Bottom line: side effect should be explicit!

> This is a follow up to OAK-4970: when defining an workspace name that doesn't match the
name of the workspace of the source repository (via the {{WORKSPACE_NAME_PROP}} system property),
upgrading is still very slow and causes the repository size to grow way too much.
