Notes for Elasticsearch Performance Considerations
Raw
elasticsearch.md

☐ Refresh Interval

☐ Hot Shards

Batch Load

☐ Refresh Interval set to 0

☐ Replicas set to 0 and increased post data load

Guidance

  • Maintain odd number of nodes to leverage 3-AZ
  • Cluster size determined by biggest index size
  • Each shard maintain 10-30 GB of data
  • Total shard count (primary shard + replica factor) should be a multiple of data nodes for even distribution
  • For small indexes, keep single primary shard and increase replica count to ensure faster response (i.e. all nodes have shard data)
