Elasticsearch is a distributed, RESTful search engine optimized for speed and relevance on production-scale workloads. You can use Elasticsearch to perform real-time search over massive datasets for applications including Vector search, Full-text search, Logs, Metrics, Application Performance Monitoring, Security Logs and more !
This repo has the official Java client for Elasticsearch.
The Java client for Elasticsearch provides strongly typed requests and responses for all Elasticsearch APIs. It delegates protocol handling to an http client such as the Elasticsearch Low Level REST client that takes care of all transport-level concerns (http connection establishment and pooling, retries, etc).
The docs/design folder contains records of the major decisions in the design of the API. Most notably:
- Object construction is based on the builder pattern.
- Nested objects can be constructed with builder lambdas, allowing for clean and expressive DSL-like code.
- Optional values are represented as
nullwith@Nullableannotations instead of the newerOptional, the Java ecosystem being still very null-based.
Please refer to the full documentation on elastic.co for comprehensive information.
