             Summary: Commands in oak-run should not implement NodeStore creation logic from scratch
                 Key: OAK-4349
                 URL: https://issues.apache.org/jira/browse/OAK-4349
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: run
            Reporter: Francesco Mari
            Assignee: Francesco Mari


Many commands in oak-run implement the same logic over and over to create a {{NodeStore}} from command line arguments. I think it would be better to have this logic in a single  place and reuse it from every command.

In OAK-4246 I proposed an approach based on URIs. Instead of specified command line arguments and flags, a connection to a specific backend could be specified using a URI with application specific schemas. On OAK-4246 I showed some examples specific to the {{SegmentNodeStore}}:

- {{segment:///path/to/dir}} opens an "old style" segment store at the specified folder.
- {{segment:tar:///path/to/dir}} opens a"new style" segment store at the specified folder.
- {{segment:tar:///path/to/dir?mm=false}} opens a "new style" segment store at the specified folder and disables memory mapped files.

A solution based on URIs can be extended to other {{NodeStore}} implementations by using other schemes like {{segment:mem}}, {{document:mongo}}, {{document:rdb}}, and so on.
