faasr_predecessors_list

Get the predecessors list, by using the graph from faasr_check_workflow

internal

Allows users to create and deploy the workflow with multiple functions
in Function-as-a-Service (FaaS) cloud computing platforms.
The 'FaaSr' package makes it simpler for R developers to use FaaS platforms by providing the following functionality:
1) Parsing and validating a JSON-based payload compliant to 'FaaSr' schema supporting multiple FaaS platforms
2) Invoking user functions written in R in a Docker container (derived from rocker), using a list generated from
the parser as argument
3) Downloading/uploading of files from/to S3 buckets using simple primitives
4) Logging to files in S3 buckets
5) Triggering downstream actions supporting multiple FaaS platforms
6) Generating FaaS-specific API calls to simplify the registering of a user's workflow with a FaaS platform
Supported FaaS platforms:
Apache OpenWhisk <https://openwhisk.apache.org/>
GitHub Actions <https://github.com/features/actions>
Amazon Web Services (AWS) Lambda <https://aws.amazon.com/lambda/>
Supported cloud data storage for persistent storage:
Amazon Web Services (AWS) Simple Storage Service (S3) <https://aws.amazon.com/s3/>.
