reindex

Reindex elasticsearch with Logstash

Sometimes, you would like to reindex your data to change your mapping or to change your index settings or to move from one server to another or to one cluster to another (think about multiple data centers for example). For the later you can use Snapshot and Restore feature but if you need to change any index settings, you need something else. With Logstash 1.5.0, you can now do it super easily using elasticsearch input and elasticsearch output.
