Hi. We have a scenario where n clients use elastic cluster. In case no data has been added to elastic we need to load data from db and cache it in elasticsearch. It would be easy in case of one client and elastic server. Can one client somehow take a lock and send the data via bulk processor to one node and data will get distributed or is there a way to load directly from oracle?

Elasticsearch has no concept of a lock like this.

Logstash + the JDBC input?
