Francesco Mari created OAK-7788:
-----------------------------------

             Summary: Measure read rate for the Segment Store
                 Key: OAK-7788
                 URL: https://issues.apache.org/jira/browse/OAK-7788
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: segment-tar
            Reporter: Francesco Mari
            Assignee: Francesco Mari
             Fix For: 1.10


In order to better understand the behaviour of the Segment Store, we should measure its read rate, defined as the amount of API calls performed by the user that might trigger a read to the underlying persistence layer. 

The outermost API we can instrument is the NodeState. Calls to this API represent a clear intention of the user to read the repository data. A lower level API would not carry the same semantics and would be ineffective for deducing the intentions of the user.
