Overview

Tuning guideline for the gzip compression threshold applied to production frontend assets during the Vite build process.

Description

The DolphinScheduler frontend build uses vite-plugin-compression to generate .gz compressed versions of production assets. The threshold is set to 10240 bytes (10 KB) — assets smaller than this are not compressed because the gzip overhead would negate any size savings. The original uncompressed files are retained alongside the .gz files to support clients that do not accept gzip encoding.

Configuration

Parameter	Value	Rationale
algorithm	gzip	Universally supported by browsers and CDNs
threshold	10240 (10 KB)	Assets below 10KB gain negligible compression benefit
ext	.gz	Standard gzip extension recognized by web servers
deleteOriginFile	false	Retains original files for non-gzip clients
verbose	true	Logs compression results during build

Source Reference

// dolphinscheduler-ui/vite.config.ts
viteCompression({
  verbose: true,
  disable: false,
  threshold: 10240,   // 10 KB minimum
  algorithm: 'gzip',
  ext: '.gz',
  deleteOriginFile: false
})
