Hi @alankar-asthana,

The creation/update is happening in https://github.com/opensearch-project/geospatial/blob/main/src/main/java/org/opensearch/geospatial/ip2geo/jobscheduler/DatasourceUpdateService.java#L63

If we can get the size of file in advance, we can calculate how much of data is processed and store the completed percentage in memory.

In GET API, we can make a call to the node who is creating or updating datasource to get the percentage value and return it in response.
