abstract class ModelConfigLoader extends Serializable with LazyLogging

Loads model configs.

Configs are resolved once when loading model data. Implement when you want to add dynamic configuration that is fetched from external source, for example OpenAPI specification and you would like this configuration to be immutable for deployed processes.

This class is optional to implement.

  15. def resolveConfig(inputConfigDuringExecution: InputConfigDuringExecution, classLoader: ClassLoader): Config

    Resolves full config used inside pl.touk.nussknacker.engine.api.process.ProcessConfigCreator.

    Resolves full config used inside pl.touk.nussknacker.engine.api.process.ProcessConfigCreator. Invoked both in NK and running process.

    Default implementation resolveConfigUsingDefaults should rather not be changed.

  16. final def resolveConfigUsingDefaults(inputConfig: Config, classLoader: ClassLoader): Config

    Default implementation of resolveConfig.

    Default implementation of resolveConfig. Loads model config the from following locations:

    • param inputConfig
    • defaultModelConfig.conf from model jar
    • reference.conf from model jar</li </ol

    Resolves config part to pass during execution while e.g.

    Resolves config part to pass during execution while e.g. process deployment on Flink cluster. When running a process (e.g. on Flink) resolved config part is used to construct full config (see resolveConfig)

    Method used for performance reasons to reduce serialized configuration size inside deployed processes. By default config from main nussknacker file at path: scenarioTypes.{type_name}.modelConfig is passed unchanged.

    inputConfig

    configuration from scenarioTypes.{type_name}.modelConfig

    returns

    config part that is later passed to a running process (see e.g. FlinkProcessCompiler)

  18. def shouldResolveEnvVariables: Boolean

    We want to be able to use model config with unresolved env variables.

    We want to be able to use model config with unresolved env variables. It is for purpose where engine (e.g. Flink) see other host names / ports than designer. It is especially useful for local development. Remember that when you turn it off, you can't use optional substitutions (e.g. ${?KAFKA_ADDRESS} in model config. Otherwise they will be removed.
