Thanks for the pointers. Yes, I'm looking to do a batch job to
reprocess all of the records in our index. Any tips on when
should we prefer scan search over scripting and vice versa for
this type of operation?
The best you can do inside of ES is with the update API, possibly
using a script, which can save you some bandwidth transferring
your whole documents.
If it turns out you need client-side processing, use a scan search
to retrieve the docs and the bulk API to index the newly
transformed docs. It's surprisingly efficient!
