…crash Wide table-model TsFiles (thousands of measurements) crashed the browser in both the Data Preview and Chart views by rendering every column/series at once. Data Preview (DataTable.vue): - Paginate field columns (default 50/page) with a column search box; render only the current column window and flatten only visible columns per row. - Enable virtual row scrolling. Chart (ChartPanel.vue, TableFilterPanel.vue, TreeFilterPanel.vue): - Default-select only the first 8 numeric fields instead of all fields on load. - Refuse to render and show a warning when a query returns more than 50 series. Backend (DataService.java): - Hard-cap chart series at 200 per request as a performance safety net. i18n: add column-pagination and chart-series-limit strings (zh-CN, en-US).
The /view/** resource handler applied max-age=3600 uniformly, so index.html (the entry point referencing content-hashed asset filenames) was cached for up to an hour. After a deploy, browsers kept loading the old index.html and thus the old asset references, masking the new build. Split the caching: - /view/assets/** (content-hashed build output): max-age=1y, public, immutable. - index.html and SPA routes: no-cache (revalidate every load) so a new deployment is picked up immediately.
