I have a source index with 14 million docs (2.5 TB). Reindexing it all at once is destabilizing the cluster and it stops midway. there is no way of tracking the progress and resuming . So i would like to know how to reindex using a certain date field. For example, i would like to reindex from year 1995 to 1998 in one go and then 1998 to 2001 in another.So that if the process stops at any time , I would be aware of where it stopped and where to resume it from.
someone talks about something like that in the above topic.
