elastic-copy

Copy data from / to elasticsearch very fast

Motivation / use case

elasticdump is a very nice tool for copying a single index to another server.

But sometimes, you need to copy more than a single index, and as fast as possible!

This why I build elasticcopy.

Multi threading

elasticcopy is fast, because it use multi threads to copy data in parallel.

The parallel unit is a shard, if you want to copy 12 indices of 3 shards, this will create 36 tasks.

Usage

elasticcopy --source=http://localhost:9200 --target=http://prod:9200 --indices=events-1,events-2 --threads=12
