Creating and CRUDing a KV Store in Splunk: Part 2

By |Published On: September 9th, 2016|

Part 2: CRUD the KV Store

In Part 1, we covered how to create a KV Store both through the UI, as well as by modifying collections.conf and transforms.conf. We also covered how to edit a KV Store directly using the Splunk Search Language. In this part, we will cover CRUDing our KV Store Collection.

Remember, we will be interacting with the Lookup Definition (task_lookup) we set up in order to CRUD the data, as we cannot interact with the KV Store (task_collection) directly when using the Splunk Search Language.


Reading is the easiest. To read all the results run:

Copy to Clipboard

And, if we want to find a specific row, all we need to do is run:

Copy to Clipboard


Go to the Splunk task app and in the default search window paste in the following:

Copy to Clipboard

This search first pulls all the values from the lookup and then pulls out the hidden _key field by running | eval key=_key. We will then run append and eval out all of our values. Format them into a table and then output the values back into the lookup.


In order to update our values, all we need to do is change our search to find the specific key we want to modify. Then we can eval out new values for our fields, like so:

Copy to Clipboard

The key part is the append=t at the end. Otherwise, we would just overwrite the lookup.


Deleting a specific value from our KV store is also easy to do:

Copy to Clipboard

Simply remove the field you don’t want based on the ID of the key and output the rest of the values back into the KV.

That’s it! You’ve now successfully created a KV Store and Lookup Definition, as well as learned how to successfully CRUD a KV Store Collection’s data.
