How to index documents in elasticsearch quickly?

Question

elasticsearch

Essence of the question:
there is a Xeon server with 16 cores and 16GB of RAM
, I installed elasticserch and I import documents into it using elasticdump,
but the process is extremely slow - about 1.5 million documents per day,
and I need to upload 810 million documents
, is it possible to speed up indexing?
Elastic is needed for fast full-text search, maybe you should look towards another engine?

Answer 1

Are you doing a separate request for each document?
Use Bulk API
