I Have 3 node Elasticsearch cluster and around 1TB data with 16 indexes and many ids. While parsing document ids may get repeated and i need to update old id by concatenating new values. I have tried importing information with single cluster and for small amount of data(approx 10GB) it took 3 weeks as their were around 30lakh ids in it. Now i want to have my complete set of data on Elasticsearch is their other way to import data? Is their any location where i can keep all data and it will be directly imported?
