Aleksandr Chesnokov updated IGNITE-27580:
-----------------------------------------
Description: System views are stored in a single data.json.js, which for
large clusters grows to hundreds of MB and freezes the browser. Split system
views data into chunked files with per-view metadata and load rows lazily in
systemViewTab.js; sorting and full-text search for system views are dropped.
(was: h2. Problem
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.
h2. Proposed solution
IGNITE-24724 Could solve the problem, but it does not help for reports
collected from previous releases of Ignite
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 and build the total view using metadata without loading all
rows at once. This should keep the report responsive for large datasets
h3. Limitations
To keep UI fast, the following features will be removed for system views:
* Sorting in HTML table,
* Text search across rows
As a workaround, users can use {{grep/jq}} over chunked JSON files.
h2. Steps to test report
# Comment PerformanceStatisticsReportSelfTest.java:177
# Run PerformanceStatisticsReportSelfTest#testCreateReport
# See modules/performance-statistics-ext/ignite/work/perf_stat)
