There is a need to start the child LogStream task from change position 0 (this feature was included in 2022.05 SP02, as a way to enable the LogStream task reading from the beginning of the last timeline created by the parent),From the Replicate UI, this is working as expected.
The problem is when trying to do the same, using the REST APIs:
- The issue is that the REST API service does not support including a stream position (SCN, LSN, etc), to do this programmatically. it does not matter if this is a child LogStream task or a regular task: the API does not support specifying a SCN/LSN position.
We implemented HA for Qlik services, during failover we load replicate server on another node and try to start tasks automatically, using REST API. we are facing an issue that child tasks fail to start because timestamp we are keeping for parent task is different from last actual timeline child task has. It would be useful to have restart option from 0 via API, this way we wouldn't need to deal with different timestamps for different tasks and when failover happens child tasks would restart smoothly.
