cluster computing - Elasticsearch query result consensus across replica nodes -


i'm working on project uses elasticsearch primary data store sensitive data needs resilient corruption. indexes split 5 shards 2 replicas across 3 machines.

is there built in way send queries 3 nodes , check consensus? need code explicitly in client or can data node happen connect handle me?

also, elasticsearch perform parity/integrity checks on source , index data, aside potentially slow startup check when index.shard.check_on_startup enabled? or need handled fault tolerant fs or in hardware raid-5/10?
