DagsterGraphQLClient
(hostname, port_number=None, transport=None)[source]¶Official Dagster Python Client for GraphQL
Utilizes the gql library to dispatch queries over HTTP to a remote Dagster GraphQL Server
As of now, all operations on this client are synchronous.
Intended usage:
client = DagsterGraphQLClient("localhost", port_number=3000)
status = client.get_run_status(**SOME_RUN_ID**)
get_run_status
(run_id)[source]¶Get the status of a given Pipeline Run
run_id (str) – run id of the requested pipeline run.
DagsterGraphQLClientError("PipelineNotFoundError", message) – if the requested run id is not found
DagsterGraphQLClientError("PythonError", message) – on internal framework errors
returns a status Enum describing the state of the requested pipeline run
PipelineRunStatus
reload_repository_location
(repository_location_name)[source]¶Reloads a Dagster Repository Location, which reloads all repositories in that repository location.
This is useful in a variety of contexts, including refreshing Dagit without restarting the server.
repository_location_name (str) – The name of the repository location
Object with information about the result of the reload request
submit_pipeline_execution
(pipeline_name, repository_location_name=None, repository_name=None, run_config=None, mode=None, preset=None, tags=None)[source]¶Submits a Pipeline with attached configuration for execution.
pipeline_name (str) – The pipeline’s name
repository_location_name (Optional[str], optional) – The name of the repository location where the pipeline is located. If omitted, the client will try to infer the repository location from the available options on the Dagster deployment. Defaults to None.
repository_name (Optional[str], optional) – The name of the repository where the pipeline is located. If omitted, the client will try to infer the repository from the available options on the Dagster deployment. Defaults to None.
run_config (Optional[Any], optional) – This is the run config to execute the pipeline with. Note that runConfigData is any-typed in the GraphQL type system. This type is used when passing in an arbitrary object for run config. However, it must conform to the constraints of the config schema for this pipeline. If it does not, the client will throw a DagsterGraphQLClientError with a message of PipelineConfigValidationInvalid. Defaults to None.
mode (Optional[str], optional) – The mode to run the pipeline with. If you have not defined any custom modes for your pipeline, the default mode is “default”. Defaults to None.
preset (Optional[str], optional) – The name of a pre-defined preset to use instead of a run config. Defaults to None.
tags (Optional[Dict[str, Any]], optional) – A set of tags to add to the pipeline execution.
DagsterGraphQLClientError("InvalidStepError", invalid_step_key) – the pipeline has an invalid step
DagsterGraphQLClientError("InvalidOutputError", body=error_object) – some solid has an invalid output within the pipeline. The error_object is of type dagster_graphql.InvalidOutputErrorInfo.
DagsterGraphQLClientError("ConflictingExecutionParamsError", invalid_step_key) – a preset and a run_config & mode are present that conflict with one another
DagsterGraphQLClientError("PresetNotFoundError", message) – if the provided preset name is not found
DagsterGraphQLClientError("PipelineRunConflict", message) – a DagsterRunConflict occured during execution. This indicates that a conflicting pipeline run already exists in run storage.
DagsterGraphQLClientError("PipelineConfigurationInvalid", invalid_step_key) – the run_config is not in the expected format for the pipeline
DagsterGraphQLClientError("PipelineNotFoundError", message) – the requested pipeline does not exist
DagsterGraphQLClientError("PythonError", message) – an internal framework error occurred
run id of the submitted pipeline run
dagster_graphql.
InvalidOutputErrorInfo
(step_key, invalid_output_name)[source]¶This class gives information about an InvalidOutputError from submitting a pipeline for execution from GraphQL.
dagster_graphql.
ReloadRepositoryLocationInfo
(status, failure_type=None, message=None)[source]¶This class gives information about the result of reloading a Dagster repository location with a GraphQL mutation.
status (ReloadRepositoryLocationStatus) – The status of the reload repository location mutation
failure_type – (Optional[str], optional): the failure type if status == ReloadRepositoryLocationStatus.FAILURE. Can be one of ReloadNotSupported, RepositoryLocationNotFound, or RepositoryLocationLoadFailure. Defaults to None.
message (Optional[str], optional) – the failure message/reason if status == ReloadRepositoryLocationStatus.FAILURE. Defaults to None.
