public interface InferenceService extends Closeable

  • Method Details

    • init

      default void init(Client client)

    • name

      String name()

    • parseRequestConfig

      void parseRequestConfig(String modelId, TaskType taskType, Map<String,Object> config, Set<String> platfromArchitectures, ActionListener<Model> parsedModelListener)
      Parse model configuration from the config map from a request and return the parsed Model. This requires that both the secrets and service settings be contained in the service_settings field. This function modifies config map, fields are removed from the map as they are read.

      If the map contains unrecognized configuration option an ElasticsearchStatusException is thrown.

      Parameters:
      modelId - Model Id
      taskType - The model task type
      config - Configuration options including the secrets
      platfromArchitectures - The Set of platform architectures (OS name and hardware architecture) the cluster nodes and models are running on.
      parsedModelListener - A listener which will handle the resulting model or failure

    • parsePersistedConfigWithSecrets

      Model parsePersistedConfigWithSecrets(String modelId, TaskType taskType, Map<String,Object> config, Map<String,Object> secrets)
      Parse model configuration from config map from persisted storage and return the parsed Model. This requires that secrets and service settings be in two separate maps. This function modifies config map, fields are removed from the map as they are read. If the map contains unrecognized configuration options, no error is thrown.
      Parameters:
      modelId - Model Id
      taskType - The model task type
      config - Configuration options
      secrets - Sensitive configuration options (e.g. api key)
      Returns:
      The parsed Model

    • parsePersistedConfig

      Model parsePersistedConfig(String modelId, TaskType taskType, Map<String,Object> config)
      Parse model configuration from config map from persisted storage and return the parsed Model. This function modifies config map, fields are removed from the map as they are read. If the map contains unrecognized configuration options, no error is thrown.
      Parameters:
      modelId - Model Id
      taskType - The model task type
      config - Configuration options
      Returns:
      The parsed Model

    • infer

      void infer(Model model, List<String> input, Map<String,Object> taskSettings, InputType inputType, ActionListener<InferenceServiceResults> listener)
      Perform inference on the model.
      Parameters:
      model - The model
      input - Inference input
      taskSettings - Settings in the request to override the model's defaults
      inputType - For search, ingest etc
      listener - Inference result listener

    • chunkedInfer

      void chunkedInfer(Model model, List<String> input, Map<String,Object> taskSettings, InputType inputType, ChunkingOptions chunkingOptions, ActionListener<List<ChunkedInferenceServiceResults>> listener)
      Chunk long text according to chunkingOptions or the model defaults if chunkingOptions contains unset values.
      Parameters:
      model - The model
      input - Inference input
      taskSettings - Settings in the request to override the model's defaults
      inputType - For search, ingest etc
      chunkingOptions - The window and span options to apply
      listener - Chunked Inference result listener

      listener - The listener

    • stop

      default void stop(String modelId, ActionListener<Boolean> listener)
