Splunk inputlookup overwrite clause11/21/2023 ![]() The name of the lookup_destfield is used. If the name of the event_destfield is the same as the lookup_destfield, you don't need to specify the event_destfield. You can specify multiple event_destfield values. event_destfield Display name in the Canvas View: Name of the New Field Syntax: AS Description: A field in the outgoing data. Example in Canvas View: The Lookup Field to Add field is set to name. All fields in the lookup dataset that are not specified in the lookup_field list are added to the outgoing DSP records. If no lookup destination fields are specified, all fields in the lookup dataset that you did not put in the lookup_field list are added to the outgoing DSP records. Used with OUTPUT | OUTPUTNEW to replace or append field values. You can specify multiple lookup_destfield values. Lookup_destfield Display name in the Canvas View: Lookup Field to Add Syntax: Description: A field in the lookup table to be applied to the outgoing data. For OUTPUTNEW mode: The Overwrite Record Fields with Lookup Values check box is clear.For OUTPUT mode: The Overwrite Record Fields with Lookup Values check box is selected.Therefore, output fields that were already in the records are overwritten with values from the lookup. In OUTPUT mode, all field names and values from the lookup dataset are added to the outgoing DSP records. In OUTPUTNEW mode, values from the lookup dataset are only added to the DSP record if that record has a null value for that field or is missing that field entirely. OUTPUT | OUTPUTNEW Display name in the Canvas View: Overwrite Record Fields with Lookup Values Syntax: OUTPUT | OUTPUTNEW Description: Select an output mode. Example in Canvas View: The Incoming Stream Field field is set to Store. ![]() The name specified in the lookup_field argument is used. If the name of the event_field is the same as the lookup_field, you don't need to specify the event_field. You can specify multiple event_field values. Optional arguments event_field Display name in the Canvas View: Incoming Stream Field Syntax: AS Description: The field that contains the values to match in the lookup_field in the lookup dataset. Example in Canvas View: The Lookup Field field is set to store_number. ![]() You can specify multiple lookup_field values, separated by commas. lookup_field Display name in the Canvas View: Lookup Field Syntax: Description: A field in the lookup dataset to match against incoming data. Example in Canvas View: The Lookup Name field is set to store_info. Before using this function, you must either upload a CSV table or connect to a Splunk Enterprise KV Store. ).] Required arguments lookup_dataset Display name in the Canvas View: Lookup Name Syntax: Description: The name of the lookup connection. Function Output collection> This function outputs the same collection of records but with a different schema S. Function Input/Output Schema Function Input collection> This function takes in collections of records with schema R. See Connect to the Splunk Enterprise KV Store using the Streams API page for information on how to tune caching in your DSP lookups. However, you do need to restart any active pipelines if you are modifying the schema of the KV Store collection.ĭSP caches KV Store lookup data for a period of time. You do not need to restart any active pipelines that are using a KV Store lookup if you are adding, updating, or deleting data in the KV Store collection. ![]()
