Rule 3: Throttle the bulk indexing load Asynchronous architecturemakes es scalable and fast, but susceptible to running out ofmemory under excessive bulk indexing load.
Rule 4: Try to make all shardsapproximately the same sizeElasticsearch allocates shards based on the number of shards. It doesn’t consider shard sizes or available disk space.
4 rules for happy elasticsearch1. Give nodes plenty of space2. Distributed but well connected3. Throttle the load4. Make all shards the same size
