Failure on using dataStoreSecrets

[jasonxu-129]

Hello, I'm trying to deploy Trino Gateway using Helm (version 1.13.0). I have populated the dataStoreSecrets section and removed the dataStore configuration from the config section. However, the final configuration still includes the default values, override/merge from dataStoreSecrets doesn't show up.

dataStore:
   driver: org.postgresql.Driver
   jdbcUrl: jdbc:postgresql://localhost:5432/gateway
   password: mysecretpassword
   user: postgres

I see code in templates/secrets.yaml

data:
    config.yaml: "{{toYaml (merge .Values.config $authenticationDict $dataStoreDict $backendStateDict ) | b64enc}}"

I'm not sure how these default values are being populated. Could someone help me understand? Thank you in advance!

@willmostly helped investigate in slack channel, he find it's due to in
merge .Values.config $authenticationDict $dataStoreDict $backendStateDict
.Values.config is populated with the custom values you supply + the default values... which contains

dataStore:
   driver: org.postgresql.Driver
   jdbcUrl: jdbc:postgresql://localhost:5432/gateway
   password: mysecretpassword
   user: postgres

the merge function does give precedence to the leftmost dictionary, the default will prevent the value from the secret from taking effect.

I'm using the workaround Will suggested now

config:
  dataStore: null
