[jira] [Commented] (OAK-1568) Provide flag to not cache documents from queries

    [ https://issues.apache.org/jira/browse/OAK-1568?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13940557#comment-13940557 ] 

Jukka Zitting commented on OAK-1568:
------------------------------------

Wouldn't a scan-resistant cache like the {{CacheLIRS}} class already be able to handle such cases?

> For some of the cases like Blob/Version Garbage Collection code logic traverses over large number of NodeDocument obtained from DocuementStore.query methods. Currently these method cache and NodeDocument obtained by default.
> For usage pattern like above this would overflow the cache and it might be better to avoid caching in such cases.
