I have

index.number_of_shards: 5

index.number_of_replicas: 1

node: 1

Answer 1

To optimize ES, there is something we can do

1.use less no of shards ( if you have more no if shards Den it performs map reduce to merge results from different shards)

2 . choose in index.store.type. By default it store index as simple file system. Use niofs for Linux and mmaps for Windows

1. Use appropriate queries. Don include more wildcard queries, use filters as much as you can.

2. Use thrift protocol.. Because it converts data in to binary so easy to transfer and faster too..
