Purpose/Overview:

Needs to support reporting that allows catalogers to know about updates on linked Bibliographic fields and Authorities over a period of time. The module will consume statistics of instance-authority links updates and provide an endpoint for fetching this data.

Requirements/Scope:

1. A new API interface created `links-statistics`

2. Endpoint GET /links/authority/stats created

3. Default sort by updated date

4. Endpoint parameters supported:
   ||parameter name||values||
   |limit|integer (default 100)|
   |fromDate|date-time (inclusive, optional)|
   |toDate|date-time (inclusive, optional)|

      4. Response:

Approach:

1. Make a request to a database with parameters and `limit + 1`

2. In response return the `limit` number of records and fill `next` with the limit+1 record date-time.

3. Make sure that updated date is indexed

Acceptance criteria:

• Endpoint created

• Covered by unit tests

• Karate tests are created/updated

• Module documentation updated

• Logging is well-defined
