Workflow

class Workflow

Workflows on Redivis are where analytical pipelines are built and executed. All workflows are owned by a user, and are made up of transforms, notebooks, and their output tables.

Workflows were previously referred to as "Projects" on Redivis. Existing code that utilized the "project" terminology will continue to work (e.g., User$list_projects()).

However, we encourage users to migrate their code to prevent future issues and confusion.

Constructors

Method	Description
redivis$current_workflow()	Get the current default workflow. Typically called within notebooks.
Organization$list_workflows([max_results])	List all workflows in the organization.
User$list_workflows([max_results])	List all workflows owned by a user.
Organization$workflow(name)	Construct a new workflow instance that references a workflow owned by an organization.
User$workflow(name)	Construct a new workflow instance that references a workflow owned by a user.

Examples

Basics

library("redivis")

workflow <- redivis$user("imathews")$workflow("example_workflow_climate_analysis")
tables <- workflow$list_tables()

for (table in tables){
    # Properties will be populated with the table.list resource representation
    print(table$properties) 
    
    table$get()
    # Properties will now be populated with the table.get resource representation
    print(table$properties) 
}

workflow$table("join_lat_lon_output")$exists() # -> TRUE

Scoped queries

Fields

properties	A named list containing the API resource representation of the workflow. This will be fully populated after calling Workflow$get(), and partially populated for worfklows created via User$list_workflows. Otherwise will be NULL.
qualified_reference	The fully qualified reference for the workflow, which can be used in SQL queries or the REST API. E.g., imathews.example_workflow_climate_analysis:x7kh
organization	A reference to the Organization instance that constructed this workflow.
scoped_reference	The canonical reference for the workflow, without the username qualifier. E.g.,: example_workflow_climate_analysis:x7kh
user	A reference to the User instance that constructed this workflow.

Methods

Workflow$datasource()	Create a reference to a datasource within the workflow.
Workflow$exists()	Check whether the workflow exists.
Workflow$get()	Get the workflow, populating the properties attribute on the current instance.
Workflow$list_datasources([max_results])	List all datasources in the workflow.
Workflow$list_notebooks([max_results])	List all notebooks in the workflow.
Workflow$list_parameters([max_results])	List all parameters in the workflow.
Workflow$list_tables([max_results])	List all tables in the workflow.
Workflow$list_transforms([max_results])	List all transforms in the workflow.
Workflow$notebook(name)	Create a reference to a specific notebook within the workflow.
Workflow$parameter(name)	Create a reference to a specific parameter within the workflow.
Workflow$query(query_string)	Create a query scoped to the workflow.
Workflow$table(table_reference)	Create a reference to a specific table within the workflow.
Workflow$transform(name)	Create a reference to a specific transform within the workflow.
