As of Aspire 4.0, Elasticsearch is a supported NoSQL database that can be used to maintain the Crawl State.
The Aspire Elasticsearch Provider is the component that is responsible for talking to Elasticsearch on behalf of Aspire. All configuration for the Elasticsearch Provider in Aspire is done in the settings.xml file.
The Elasticsearch NoSQL Provider for Aspire requires Elasticsearch 7.x to run. It does not run with previous versions.

Aspire will create one set of Elasticsearch indexes for each content source configured. When the content source is deleted, the indexes will be dropped. The index name has following structure:
Examples of index names: aspire-dev-aspider_web_crawler-processqueue, aspire-dev-aspider_web_crawler-snapshot, aspire-dev-group_expansion_manager-usersandgroups

Elasticsearch provider can be configured to use Basic authentication if required by the Elasticsearch server administrator. Username and password must be provided. Password must be encrypted by standard Aspire encryption utilities.
