If-Else Pipeline

In the realm of Syncraft, the If-Else Pipeline acts as a decision-maker, orchestrating the flow of logic based on certain conditions. This pipeline is paramount when the data processing logic needs to diverge based on specific predicates.

Core Components:

The If-Else Pipeline is structured around three primary components:

Condition: A predicate query that dictates the course of action.
Then: The pipeline to be executed if the condition holds true.
Else: The pipeline to be executed if the condition holds false.

    {
        "query": {
            "id": {
                "eq": 2
            }
        },
        "selection": {
            "id": true,
            "name": true
        },
        "root": "Users"
    },
    {
        "if": {
            "id": {
                "eq": 21
            }
        },
        "then": {
            "query": {
                "id": {
                    "eq": 4
                }
            },
            "selection": {
                "id": true,
                "name": true
            },
            "root": "Users"
        },
        "else": {
            "query": {
                "id": {
                    "eq": 1
                }
            },
            "selection": {
                "id": true,
                "name": true,
                "active": true
            },
            "root": "Users"
        }
    }
]

Workflow:

Condition Evaluation: The if block contains the condition to be evaluated. In the example above, it checks if the id field equals 21.
Then Execution: If the condition is true, the then block is executed. Here, it queries for a user with id equal to 4 and selects the id and name fields from the Users root.
Else Execution: If the condition is false, the else block is executed. In this scenario, it queries for a user with id equal to 1 and selects the id, name, and active fields from the Users root.

Integration:

The If-Else Pipeline can seamlessly blend within a larger query pipeline structure, facilitating condition-driven logic flows. It can be nested within higher-order pipelines like Serial, Parallel, or Race pipelines to further fine-tune the logic flow, making the query engine versatile and adaptive to varying data scenarios.
