Chetan Mehrotra commented on OAK-6081:
--------------------------------------
Currently it uses normal IndexEditors. For Lucene the editor uses a
FSDirectoryFactory so index files get stored on file system. To support other
indexes we need to think of a way to store the index data outside of NodeStore.
We can use a SegmentStore or a flat file to store the index data and then need
to provide a corresponding importer to read that index data and apply it to
actual NodeStore

> Key: OAK-6081
> URL: https://issues.apache.org/jira/browse/OAK-6081
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: indexing, run
> Reporter: Chetan Mehrotra
> Assignee: Chetan Mehrotra
> Fix For: 1.8
>
>
> To enable better management for indexing related operation specially around
> reindexing indexes on large repository setup we should implement some tooling
> as part of oak-run
> The tool would support
> # *Resumable tarversal* - It should be able to reindex large repo with
> resumable traversal such that even if indexing breaks due to some issue it
> can resume from last state (OAK-5833)
> # *Multithreaded traversal* - Current indexing is single threaded and hence
> for large repo it can take long time. Plan here is to support multi threaded
> indexing where each thread can be assigned a part of repository tree to index
> and in the end the indexes are merged
> # For DocumentNodeStore setup it would be possible to connect oak-run to a
> live cluster and it would take care of indexing -> storing index on disk ->
> merging index -> importing it back at end. This would ensure that live setup
> faces minimum disruption and is not loaded much
> # For SegementNodeStore setup it would be possible to index on a cloned setup
> and then provide a way to copy the index back
