Hi @POOJITHA Behara,

when you have a node-level data page and multiple nodes available, the data page gets loaded one time per node. This means that Pega leverages the distributed architecture to efficiently retrieve data.

Multiple Nodes: If you have multiple nodes in your Pega cluster, each node will handle the loading of the data page independently. Thus, the data page will be loaded separately on each node when it is first accessed on that node

Example Scenario

Assume you have a Dev environment with 3 nodes:

• Node A: The data page is accessed for the first time by a requestor, and the data page is loaded into memory on Node A.
• Node B: The data page is accessed for the first time by a requestor, and the data page is loaded into memory on Node B.
• Node C: The data page is accessed for the first time by a requestor, and the data page is loaded into memory on Node C.

In this scenario, the data page will be loaded three times in total—once on each node

Benefits of Node-Level Data Page Loading:

• Scalability: Distributing the load across nodes improves performance when dealing with large datasets or high user traffic.
• Data Consistency: Each node has its own copy, reducing the risk of data inconsistencies that might arise from multiple processes trying to access a single data source
