class Runner

Bases: object

A method for running a Pipeline.

This can be subclassed to provide the ability to run on different cloud providers, etc.

__init__()

Methods

__init__()
get_split_ind()	Get the split_ind for the process.
run(cfg_json_uri, pipeline, commands[, ...])	Run commands in a Pipeline using a serialized PipelineConfig.
run_command(cmd)	Run a single command.

get_split_ind() → int | None

Get the split_ind for the process.

For split commands, the split_ind determines which split of work to perform within the current OS process. The CLI has a –split-ind option, but some runners may have their own means of communicating the split_ind, and this method should be overridden in such cases. If this method returns None, then the –split-ind option will be used. If both are null, then it won’t be possible to run the command.

Return type:

int | None
