bobbai00 opened a new issue, #3928:
URL: https://github.com/apache/texera/issues/3928
### Feature Summary
The computing unit master Docker image
(`bin/computing-unit-master.dockerfile`) currently installs R dependencies by
default, which significantly increases the image size and build time. There
should be a build argument to conditionally enable/disable R support based on
deployment requirements.
### Proposed Solution or Design
Add a `WITH_R_SUPPORT` build argument to
`bin/computing-unit-master.dockerfile` and
`bin/computing-unit-worker.dockerfile` that:
1. **Defaults to `true`** for backward compatibility with existing
deployments
2. **Conditionally installs R dependencies** when set to `true`:
- R-related system packages (gfortran, libreadline, libxml2, etc.)
- R language (version 4.3.3) compilation and installation
- R packages (coro, dplyr, arrow)
- R requirements from `r-requirements.txt`
3. **Skips R installation** when set to `false`:
- Only installs Python dependencies and core system packages
- Significantly reduces image size and build time
### Impact / Priority
(P2)Medium – useful enhancement
### Affected Area
Deployment / Infrastructure
