Configure - Starlark Roadmap

[jbedard]

Incremental updates

• Minimal processing when only updating a single directory (ongoing)
  • Starlark exports hook for indexing without re-generating rules
• Rule index caching (part1)
• IDE plugin or daemon process to manage caching and incremental updates

Performance (ongoing)

• Concurrency (including: 1893)
• FS traversal (including: 1166/1908, 1893))
• [x] .bazelignore perf ~1890~, ~1886~
• [x] Run all starlark extensions in parallel
• [x] Run all queries (tree-sitter, jq, regex, ...) in parallel

Requests

• BUILD-generation unit test framework
• .star unit test framework, this may require splitting files so aspect.register_configure_extension is not in the file being tested
