Amit Jain reassigned OAK-7083:
------------------------------
Assignee: Amit Jain (was: Matt Ryan)
> CompositeDataStore - ReadOnly/ReadWrite Delegate Support
> --------------------------------------------------------
>
> Key: OAK-7083
> URL: https://issues.apache.org/jira/browse/OAK-7083
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: blob, blob-cloud, blob-cloud-azure, blob-plugins
> Reporter: Matt Ryan
> Assignee: Amit Jain
> Priority: Major
>
> Support a specific composite data store use case, which is the following:
> * One instance uses no composite data store, but instead is using a single
> standard Oak data store (e.g. FileDataStore)
> * Another instance is created by snapshotting the first instance node store,
> and then uses a composite data store to refer to the first instance's data
> store read-only, and refers to a second data store as a writable data store
> One way this can be used is in creating a test or staging instance from a
> production instance. At creation, the test instance will look like
> production, but any changes made to the test instance do not affect
> production. The test instance can be quickly created from production by
> cloning only the node store, and not requiring a copy of all the data in the
> data store.
