Dynamic Environment
To load environment variables into the configuration you can use the dynamic.env.config
property key to list all the property names that will need templating at run time. Pinot will lookup the in the environment for the variable specified as value and insert the contents in the configuration.
Example:
Following an example where we first load some variables in the ENV and then we specify in the config what needs to be templated and with which variable.
export PINOT_CONTROLLER_HOST=host
export PINOT_SERVER_PROPERTY=property
export ANOTHER_VARIABLE=random
Config from CLI or Config Path
dynamic.env.config=pinot.controller.host,pinot.server.property,other.var
pinot.controller.host=PINOT_CONTROLLER_HOST
pinot.server.property=PINOT_SERVER_PROPERTY
other.var=ANOTHER_VARIABLE
Final result (in memory)
dynamic.env.config=pinot.controller.host,pinot.server.property,other.var
pinot.controller.host=host
pinot.server.property=property
other.var=random
