[jira] [Commented] (OAK-377) Data store garbage collection

    [ https://issues.apache.org/jira/browse/OAK-377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13817222#comment-13817222 ] 

Michael Marth commented on OAK-377:
-----------------------------------

I think both these suggestions are useful.
Does it make sense to make the DSGC specific to MKs? I am thinking that the MongoMK could leverage a native Mongo index for references.

> Unused binaries in the data store need to be garbage collected.
> There is a partial implementation in oak-mk, however it is currently not run (not run automatically, and I think there is no way to run it manually).
> Also, we might want to investigate in faster garbage collection algorithms: young generation garbage collection, or garbage collection using reference counting (for example using an index of references to the data store).
