Auto Values

Hydrolix has automatic values that can be included within a transform, listed below.

Additionally, there are WURFL-related auto values available for device identification when WURFL is enabled.

Auto Value Name	Description	Stream	Kafka	Batch
`current_time`	Current time	Yes	Yes	Yes
`index_pool`	Pool name used by the indexer (stream peer, kafka peer, batch peer)	Yes	Yes	Yes
`input_filename`	For batch only, specify the filename indexed. The filename is the full s3 path: s3://bucket/folder/subfolder/filename.csv	No	No	Yes
`intake_method`	Specify the intake method (Batch, Stream / Kafka)	Yes	Yes	Yes
`intake_pool`	Pool name used by the intake service. Blank if unassigned.	Yes	Yes	Yes
`kafka_topic`	Specify the Kafka topic used to index the data	Yes	No	No
`project_name`	Name of the project where the data will be indexed	Yes	Yes	Yes
`project_revision`	Revision number of the project where the data will be indexed	Yes	Yes	Yes
`project_uuid`	UUID of the project where the data will be indexed	Yes	Yes	Yes
`receive_time`	Time when the data is received	Yes	Yes	Yes
`table_name`	Name of the table where the data will be indexed	Yes	Yes	Yes
`table_revision`	Revision number of the table where the data will be indexed.	Yes	Yes	Yes
`table_uuid`	UUID of the table where the data will be indexed	Yes	Yes	Yes
`transform_name`	Name of the transform used to index the data	Yes	Yes	Yes
`transform_revision`	Revision number of the transform used to index the data	Yes	Yes	Yes
`transform_type`	Transform type (csv or json).	Yes	Yes	Yes
`transform_uuid`	UUID of the transform used to index the data.	Yes	Yes	Yes
`input_filename_segment_[0-12]`	Extract part of the filename with batch/autoingest where the separator is `/` Example: `s3://bucket/folder/subfolder/filename.csv` `s3 = input_filename_segment_0` `bucket = input_filename_segment_2` `folder = input_filename_segment_3` `subfolder = input_filename_segment_4` `filename.csv = input_filename_segment_5`	No	No	Yes

To use these automatic values, add definitions like the following in your transform:

{
    "name": "filename",
    "datatype": {
        "type": "string",
        "index": true,
        "source": {
            "from_automatic_value": "input_filename"
        }
    },
},

The source should be from_automatic_value, and the value name should be from the table above.
