helm noob question, is it possible to install Datahub via helm without referencing the datahub-prerequisite chart? (meaning, the supporting components will be separately created)

That's effectively what I'm doing. I still use helm to install prerequisite, but I

helm install

both independently. When I install

datahub

, I use those values:

datahub:
  global:
    datahub:
      managed_ingestion:
        enabled: false
    kafka:
      bootstrap:
        server: "datahub-prerequisites-kafka:9092"
      zookeeper:
        server: "datahub-prerequisites-zookeeper:2181"
      schemaregistry:
        url: "<http://datahub-prerequisites-cp-schema-registry:8081>"

    neo4j:
      host: "datahub-prerequisites-neo4j-community:7474"
      uri: "<bolt://datahub-prerequisites-neo4j-community>"

    sql:
      datasource:
        host: "datahub-prerequisites-mysql:3306"
        hostForMysqlClient: "datahub-prerequisites-mysql"
        url: "jdbc:<mysql://datahub-prerequisites-mysql:3306/datahub?verifyServerCertificate=false&useSSL=true&useUnicode=yes&characterEncoding=UTF-8&enabledTLSProtocols=TLSv1.2>"

great, thanks for the tip!

Yes! Just need to update the variables! values.yaml is a default that works out of the box, you can rewire it to any persistence layer like a managed elasticsearch, mysql, or kafka
