How many times Data page gets loaded?
Hi guys,
What if there are multiple nodes available and your data page is a node level data page then how many times dpage is loaded.

Hi @BEHARAP9, Node level D_Page will gets loaded when a particular requestor uses the D_Page. For example: There are 10 different NODES available. 1. One User logs in through WEB NODE and D_Page gets initiated when we initiate a casetype. 2. Lets assume Job Scheduler runs on UTIL NODE by calling same D_Page. Now in this case D_Page gets loaded in 2 Nodes only not on all 10 nodes. If a second user logs in to a different WEB NODE and uses the D_Page then it will load on that NODE again for first time and serves for other requestors logging in same NODE. Thanks

Hi @BEHARAP9,
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

@BEHARAP9 In multinode environement data page only loads one time per node. I f that node is in use then it will load for that node. It totally depends on node access. Thanks, Somil
