About datasets in Splunk Light

A dataset is a collection of data that you define and maintain for a specific business purpose. It is represented as a table, with fields for columns and field values for cells. You can view and manage datasets with the Datasets listing page.

The Splunk Datasets Add-on is installed by default in Splunk Light, and the Datasets listing page is available from the menu bar.

Dataset types

You can work with three dataset types. Two of these dataset types, lookups and data models, are existing knowledge objects that have been part of the Splunk platform for a long time. Table datasets, or tables, are a new dataset type that you can create and maintain.

Use the Datasets listing page to view and manage your datasets. See View and manage datasets in Splunk Light in this manual.


The Datasets listing page displays two categories of lookup datasets: lookup table files and lookup definitions. It lists lookup table files for .csv lookups and lookup definitions for .csv lookups and KV Store lookups. Other types of lookups, such as external lookups and geospatial lookups, are not listed as datasets.

You upload lookup table files and create file-based lookup definitions through the sidebar Lookups page. See Use lookups in Splunk Light in this manual.

Data model datasets

Data models are made up of one or more data model datasets. When a data model is composed of multiple datasets, those datasets are arranged hierarchically, with a root dataset at the top and child datasets beneath it. In data model dataset hierarchies, child datasets inherit fields from their parent dataset but can also have additional fields of their own.

You create and edit data model dataset definitions with the Data Model Editor. See About data models in Splunk Light in this manual.

Note: In previous versions of the Splunk platform, data model datasets were called data model objects.

Table datasets

Table datasets, or tables, are focused, curated collections of event data that you design for a specific business purpose. You can derive their initial data from a simple search, a combination of indexes and source types, or an existing dataset of any type. For example, you could create a new table dataset whose initial data comes from a specific data model dataset. After this new dataset is created, you can modify it by updating field names, adding fields, and more.

You define and maintain datasets with the Table Editor, which translates sophisticated search commands into simple UI editor interactions. It is easy to use, even if you have minimal knowledge of Splunk search processing language (SPL).

Datasets gives you the ability to create and edit table datasets. See About table datasets in Splunk Light in this manual.
