> Key: ATLAS-4738
> URL: https://issues.apache.org/jira/browse/ATLAS-4738
> Project: Atlas
> Issue Type: Improvement
> Components: atlas-core
> Reporter: Radhika Kundam
> Assignee: Radhika Kundam
> Priority: Major

> # Though there is no issues with SOLR, on Atlas startup Index recovery is
> getting started as it's considering 1970-01-01T00:00:00Z as default recovery
> start time.
> When no index recovery data is available by default it'll consider
> recovery start time based on TTL i.e., (current time - tx.log TTL).
> By default SOLR tx.log default ttl is configured as 10days.
> 2. Custom start time configuration atlas.graph.index.recovery.start.time is
> not working as it conflicts with janusgraph internal configurations. This
> config should be updated to *atlas.index.recovery.start.time*
> 3. When SOLR went down with existing architecture we note down start time
> with a buffer of solr health checkup frequency which will be (current time -
> retrytime of solr health). To avoid any possible corner case scenarios
> updating the buffer two times of retry time so next recovery start time
> should be (current time - 2 * retry time)
> 4. Added REST support for index recovery which can give more flexibility to
> the customer to start index recovery on-demand and will be valubale feature.
> a. Get index recovery timing details
> API: GET api/atlas/v2/indexrecovery/
> Response:
> { "Latest start time": "2023-03-25T20:34:59.704Z", => Start
> time of recent/upcoming Index recovery
> "On-demand start time":
> "2023-03-24T06:17:23.656Z", => Start time of index recovery requested through
> REST API
> "Previous start time":
> "2023-03-25T20:24:51.583Z" => Start time of previous index recovery
> }
> b. Start index recovery at a specific time
> API: POST
> api/atlas/v2/indexrecovery/start?startTime=2023-03-24T06:17:23.656Z
> Response:
> On success => 200 OK
> On empty start Time => 400 Bad request
> On Index recovery failure => 500 Internal Server Error
