Elasticsearch performance optimizations
ECE ECK Elastic Cloud Hosted Self Managed
Elasticsearch's default settings provide a good out-of-box experience for basic operations like full text search, highlighting, aggregations, and indexing.
However, there are a number of optimizations you can make to improve performance for your use case. This section includes both deployment-level configuration suggestions and usage-level guidance to optimize the performance of your cluster.
Use the following topics to explore relevant strategies:
- General recommendations
- Tune for indexing speed
- Tune for search speed
- Tune approximate kNN search
- Tune for disk usage
- Size your shards
Many Elasticsearch options come with different performance considerations and trade-offs. The best way to determine the optimal configuration for your use case is through testing with your own data and queries.
