--------------------------------
Fix Version/s: (was: 1.4)
> DataStoreBlobStore: chunk ids should not contain the size
> ---------------------------------------------------------
>
> Key: OAK-2466
> URL: https://issues.apache.org/jira/browse/OAK-2466
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Labels: datastore, performance
>
> The blob store garbage collection (data store garbage collection) uses the
> chunk ids to identify binaries to be deleted. The blob ids contain the size
> now (<contentHash>#<size>), and the blob id is currently equal to the chunk
> id.
> It would be more efficient to _not_ use the size, and instead just use the
> content hash, for the chunk ids. That way, enumerating the entries that are
> in the store is potentially faster. Also, it allows us to change the blob id
> in the future, for example add more information to it (for example the
> creation time, or the first few bytes of the content) if we ever want to.
