I am experiencing an issue with the DHIS2 Data Visualizer, where it continuously loads without displaying any results. I suspect that the problem is caused by the large number of Category Option Combinations (COCs) in my dataset, which exceeds 2 million entries. When I generate pivot tables using other datasets with fewer COCs, the visualizer works without any problems. However, when I attempt to visualize data from this specific dataset with 2M+ COCs, the system gets stuck in an endless loading state.
The DHIS2 instance is hosted on an AWS EC2 m5.4xlarge instance (16 vCPUs, 64GB RAM) with a 1TB volume. Despite this high-performance setup, the dataset does not load successfully in the Data Visualizer, suggesting a potential issue with either the query execution time, system resource allocation, or how DHIS2 handles large COC datasets in analytics processing.
