ElasticSearch
Distributed search and analytics are provided by Elasticsearch, an open-source engine for indexed data.
About ElasticSearch
Elasticsearch is a distributed search and analytics engine that stores structured, unstructured, and vector data in real time. It supports full-text, semantic, hybrid, and geospatial search, along with real-time aggregation for observability, security analytics, and AI retrieval use cases.
Data can be ingested through APIs, language clients, connectors, and pipelines. It can run as an on-premises download, as hosted deployments on AWS, Google Cloud, and Azure, or as a managed serverless offering, with cross-cluster search and tiered storage including searchable snapshots on object storage.
