Workflow
Configure workflows as per requirements
Overview
Workflows are a series of steps that moves a process from one state to another state by actions performed by different kind of Actors - Humans, Machines, Time based events etc. to achieve a goal like onboarding an employee, or approve an application or granting a resource etc. The egov-workflow-v2 is a workflow engine which helps in performing these operations seamlessly using a predefined configuration.
Pre-requisites
Before you proceed with the documentation, make sure the following pre-requisites are met -
Java 17
Kafka server is up and running
egov-persister service is running and has a workflow yml added yo persister config path.
PostgreSQL server is running and a database is created to store workflow configuration and data
Key Functionalities
Always allow anyone with a role in the workflow state machine to view the workflow instances and comment on it
On the creation of workflow, it will appear in the inbox of all employees that have roles that can perform any state transitioning actions in this state.
Once an instance is marked to an individual employee it will appear only in that employee's inbox although point 1 will still hold true and all others participating in the workflow can still search it and act if they have the necessary action available to them
If the instance is marked to a person who cannot perform any state transitioning action, they can still comment/upload and mark to anyone else.
Overall SLA: SLA for the complete processing of the application/Entity
State-level SLA: SLA for a particular state in the workflow
egov.wf.default.offset
The default value of offset in search
egov.wf.default.limit
The default value of limit in search
egov.wf.max.limit
The maximum number of records that are returned in search response
egov.wf.inbox.assignedonly
Boolean flag if set to true default search will return records assigned to the user only, if false it will return all the records based on the user’s role. (default search is the search call when no query params are sent and based on the RequestInfo of the call, records are returned, it’s used to show applications in employee inbox)
egov.wf.statelevel
Boolean flag set to true if a state-level workflow is required

Deployment Details
Deploy the latest version of eGov-workflow-V2 service
Note: This video will give you an idea of how to deploy any Digit-service. Further you can find the latest builds for each service in out latest release document here.
Add BusinessService Persister YAML path in persister configuration
Add Role-Action mapping for BusinessService APIs
Overwrite the egov.wf.statelevel flag ( true for state level and false for tenant level)
Create businessService (workflow configuration) according to product requirements
Add Role-Action mapping for /processInstance/_search API
Add workflow persister yaml path in persister configuration
Configuration Details
For configuration details, refer to the links in Reference Docs.
Integration Details
Integration Scope
The workflow configuration can be used by any module which performs a sequence of operations on an application/Entity. It can be used to simulate and track processes in organisations to make it more efficient too and increase accountability.
Integration Benefits
Role-based workflow
An easy way of writing rule
File movement within workflow roles
Integration Steps
To integrate, the host of eGov-workflow-v2 should be overwritten in the helm chart.
/process/_search should be added as the search endpoint for searching workflow process Instance objects.
/process/_transition should be added to perform an action on an application. (It’s for internal use in modules and should not be added in Role-Action mapping).
The workflow configuration can be fetched by calling _search API to check if data can be updated or not in the current state.
