------------------------------------------------
Summary: Directed Acyclic Graph of command execution
Key: CHAIN-113
URL: https://issues.apache.org/jira/browse/CHAIN-113
Project: Commons Chain
Issue Type: New Feature
Reporter: Muhammad Shakhawat Hossain
Hello Maintainers and contributors,
Just sharing the idea here for now. Based on the feedback, I would start
working on the implementation.
In one of my projects, I need to execute some commands in parallel with some
pre-requisite command dependencies. Essentially instead of executing the
commands in a sequential manner, it would form a DAG (Directed Acyclic Graph)
of command.
The command chain would look like below -
start -> A -> \{B, C} -> \{E -> F, G} -> end
Currently, it can be achieved through grouping commands together inside another
command and then custom parallel invocation. But what would be great is to have
a way of defining the commands as DAG and the framework would take care of the
command execution fulfilling the dependencies.
I believe this is a very common use case in API development. Where some tasks
need to be executed in sequence, some are parallelized with acyclic
dependencies.
