In the bootstrap_mce.json, SampleKafkaDataset --> SchemaMetadata --> fields, the 1st field definition is

"fields": [
                {
                  "fieldPath": "[version=2.0].[type=boolean].field_foo_2",
                  "jsonPath": null,
                  "nullable": false,
                  "description": {
                    "string": "Foo field description"
                  },
                  "type": {
                    "type": {
                      "com.linkedin.pegasus2avro.schema.BooleanType": {}
                    }
                  },
                  "nativeDataType": "varchar(100)",
                  "globalTags": {
                    "tags": [{ "tag": "urn:li:tag:NeedsDocumentation" }]
                  },
                  "recursive": false
                },
....
]

I checked the type for fieldPath, it's declared just as:

fieldPath: SchemaFieldPath

..and SchemaFieldPath is defined as:

typeref SchemaFieldPath = string

Question: Is there any significance of mentioning

version

and

type: boolean

in the SchemaFieldPath:

"[version=2.0].[type=boolean].field_foo_2"

?

Hi @witty-keyboard-20400, Please checkout this link which describes the significance of type annotated paths - https://datahubproject.io/docs/advanced/field-path-spec-v2. In short, type helps with disambiguation of a specific field.
