A company is planning to migrate its deployment environment from on-premises cluster to a Runtime...

When migrating from an on-premises cluster to a Runtime Fabric (RTF) cluster, and needing to enable Mule applications to store and share data across application replicas and restarts, the use of Anypoint Object Store V2 is the most suitable option. Here’s why and how to implement it:

Understanding Object Store V2:

Object Store V2 is designed to store and retrieve key-value pairs in a scalable and highly available manner. It is particularly useful for sharing state and data between different instances of applications running on RTF.

Setting Up Anypoint Object Store V2:

First, ensure that your MuleSoft Anypoint Platform account has access to Object Store V2.

Configure your Mule application to use Object Store V2 by defining an object store in your Mule configuration file. This can be done using the objectstore element in your Mule flow.

Configuration Steps:

Add the Object Store connector to your Mule project.

Define the object store configuration in your Mule flow as follows:

xml

Use the object store in your flows to store and retrieve data:

xml

Deploying on RTF:

Deploy your Mule application to the RTF cluster. The RTF will handle scaling and ensure that the Object Store V2 is available to all instances of your application.

Benefits:

Object Store V2 ensures data is shared and persisted across different application replicas and restarts, which meets the requirement of storing and sharing data across application replicas in the RTF cluster.
