We would like a method to set a job to backfill data for any of our collections. This way, we can set an ingestion time period, run a job to pull an update of data for a particular collection. For example, for Jira and Bit Bucket, we may need older information/events pulled into SEI so that we have accurate data to utilize. We understand that this may be a hardware/resource intensive process, so we would expect some limits to be involved, but we feel that this would help us self-manage our data easier, especially if there are updates to the source data.
