Which operation from object store will retrieve all the key value pairs? in MuleSoft 370

Which operation from object store will retrieve all the key value pairs? in MuleSoft

In MuleSoft 4, the operation you'll use to retrieve all key-value pairs from an Object Store is "retrieve all". Here's a breakdown of how it works and how to use it in your Mule flows:

Object Store Retrieve All Operation:

  • The retrieve all operation retrieves all key-value pairs stored within a specific Object Store.

  • It doesn't require any input parameters.

  • The output of the operation is a list containing objects, where each object represents a key-value pair.

Using Retrieve All in MuleSoft 4:

  1. Object Store Connector: Drag and drop the Object Store connector from the Mule palette onto your flow canvas.

  2. Configure Connection: Provide the necessary configuration details for your Object Store instance, including the URL, username, and password.

  3. Retrieve All Operation: Select the "Retrieve All" operation from the dropdown menu within the Object Store connector.

  4. Output Handling: Connect the "retrieve all" operation to subsequent processors in your flow to handle the retrieved list of key-value pairs.

Example Flow:


<flow name="RetrieveAllFromObjectStore">

    <object-store:retrieve-all config-ref="ObjectStoreConfig">

    <logger message="Retrieved key-value pairs: #[payload]" level="INFO" />



  • This flow retrieves all key-value pairs from the Object Store configured with the reference name "ObjectStoreConfig."

  • The retrieved list is then logged to the console using the logger component, displaying the message "Retrieved key-value pairs: #[payload]" along with the actual list contents.

Additional Considerations:

  • While retrieve all retrieves all existing entries, you can leverage filtering mechanisms within subsequent processors to filter the retrieved list based on specific criteria if needed.

  • For retrieving a single key-value pair based on a known key, use the retrieve operation instead.

By understanding the retrieve all operation and its usage within MuleSoft 4 flows, you can effectively retrieve and manage all key-value pairs stored in your Object Store.
