Subject [jira] [Commented] (OAK-80) Implement batched writing for KernelNodeStore
Date Wed, 02 May 2012 14:26:52 GMT

    [ https://issues.apache.org/jira/browse/OAK-80?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13266587#comment-13266587

Jukka Zitting commented on OAK-80:
----------------------------------

bq. the long term goal

Ah yes, you're right. Anyway, I don't see how that's relevant to this issue.

bq. the implementation in the MK would be quite complicated

The complexity is more or less the same regardless of whether we implement this above or below
the MK interface.

Anyway, Michael made a good point above, so let's just forget about pushing this below the
MK interface for now.

> Currently KernelNodeStore and KernelNodeStateBuilder directly apply every operation on
the content tree to the private branch of the Microkernel. There have been some concerns re.
performance hits due to network latency in the case where the Microkernel is not co-located.

> I suggest to add batching capabilities such that operations are only written through
to the Microkernel on certain limits.
