Hello,
I have index01 that is created by streaming data. The incoming date field is in milliseconds since the epoch but not being interpreted as a date-time field by OpenSearch. I would like to re-create the entire index (or maybe I can re-create a portion of the index and "Join" with the original index?) and in the process format the date-time to epoch_millis.
I found the below snippet of code which I think I need to use but I have no idea how I would use below to create index02 from index01?
