Connect Elasticsearch Data

Add the Elasticsearch connector

ddn connector init elasticsearch -i

Optional Check this repo for a docker-compose setup for Elasticsearch local instance.

Optional Load a sample dataset into Elasticsearch

npx create-elasticsearch-dataset --dataset=books

• Select hasura/elasticsearch and accept the default port by pressing “return”.

You’ll need a Elasticsearch Connection String to connect to the database; it takes this form:

http://<host>:<port>
http://local.hasura.dev:9200

The CLI will also ask for the ELASTICSEARCH_USERNAME and ELASTICSEARCH_PASSWORD. Enter the relevant values.

Note: If you are using Elastic Cloud, you might also need to configure the ELASTICSEARCH_API_KEY.

Feel free to skip the remaining environment variables.

Introspect your data source

Introspect your data source to create a set of configuration files describing your data source in a format which the connector specifies.

ddn connector introspect elasticsearch

Add your resources to create metadata for models, commands, and relationships in your supergraph.

ddn model add elasticsearch "*"

Build your supergraph for the local engine

Create a Hasura DDN project to get PromptQL running, even if you are on local dev

Head to your local DDN console
