--------------------------------------------
Summary: [perfStat] Reduce memory usage in system views report
generation
Key: IGNITE-27580
URL: https://issues.apache.org/jira/browse/IGNITE-27580
Project: Ignite
Issue Type: Sub-task
Reporter: Aleksandr Chesnokov
Assignee: Aleksandr Chesnokov
The PerfStat HTML report stores all system views data in a single data.json.js
file. For large clusters this file can be hundreds of MB, which causes long
load times and Chrome freezes due to parsing and rendering huge arrays.
Split system views data into small chunked JSON files and add a meta.json per
view (columns, row counts per node, chunk size). Update systemViewTab.js to
load rows lazily (server-side pagination) and build the total view using
metadata without loading all rows at once. This should keep the report
responsive for large datasets
