Split Processor

This processor splits a document into multiple one based on the split strategy (configurable). The current implemented strategies are:

Split Strategies

Multi-value field

• Takes a multi-value field and create a document for each value.
• The rest of the fields are copied as they come.
• Each value in the multi-value field is copied to a configurable output value.

For example, let's assume the following document:

{
  "arrayField":["a", "b", "c"],
  "otherField": "d"
}

If the arrayField is set as the split field, the it will produce three documents:

[
    {
      "arrayField":["a", "b", "c"],
      "otherField": "d",
      "outputField": ["a"]
      
    },
    {
      "arrayField":["a", "b", "c"],
      "otherField": "d",
      "outputField": ["b"]
    },
    {
      "arrayField":["a", "b", "c"],
      "otherField": "d",
      "outputField": ["c"]
    }
]

Configuration

Example configuration in a processor:

{
  "strategy":"multiValueField",
  "splitField":"fieldToSplitOn",
  "outputField":"fieldAfterSplit",
  "name": "Split processor",
  "type": "split-processor"
}

Configuration parameters:

strategy

(Required, String) Split strategy to use.

splitField

(Required, String) The name of the multi-value field to split on.

outputField

(Required, String) The name of the field where each value of the output field is copied to.
