Norberto Leite commented on OAK-2984:
-------------------------------------
Hi [~243826], I would expect, perhaps just a marginal small test/environment,
but some improvement on large dataset.
Having separate disk should magnify does results although significant
improvement would only be detected on saturated IO bound disks.
I'll take the action of review the test case and rerunning on a large dataset.
I'll let you know about it.

> Set blobs collection on separate database

> Key: OAK-2984
> URL: https://issues.apache.org/jira/browse/OAK-2984
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: mongomk
> Reporter: Norberto Leite
> Labels: performance
>
> MongoDB allows the creation of several different database namespaces to allow
> concept separation, between different applications and separate workloads to
> perform conceptual and physical isolation.
> It also allows different databases to be set on [different mount points |
> http://docs.mongodb.org/manual/reference/configuration-options/#storage.directoryPerDB]
> which for this particular workload (nodes vs blobs) would be greatly
> appreciated. Having different physical disks would be to avoid IO contention
> provoked by demanding large blob operations upload operations on disk level.
> The implementation details would be as simple has defining an option that
> would require a *blobs database name*
> N.
