I have an existing indice and want to multiply this data with a small modification to it, simply increment a few fields, but the rest of the data can remain the same. Hence, I am not looking to actually change the mappings of the indice, but simply to copy it on top of what's existingly there.
This way I could just restore the data from a SNAPSHOT with 2x shard count before re-indexing onto itself. I was wondering that since there isn't any mapping modification, would it be possible to index an indice onto itself?
The Update API modifies the data and replaces the old one. I would like to modify the data and to copy it on top of the original data.
I could use reindex API to a new index and then use aliases for queries to point to both indices. I was just wondering if it would be possible to reindex to itself instead?
