## Summary
Under high OTLP ingest volume, the whole decode, transform, and enrich
pipeline runs on the request event loop, so a single CPU core becomes
the ceiling while the rest sit idle. This adds an opt-in worker pool
that moves decode, transform, and LLM-cost enrichment onto worker
threads, keeping the main thread free for I/O. It is off by default
(`OTEL_TRANSFORM_WORKER_POOL_ENABLED`), so behavior is unchanged unless
enabled.
## Design
Workers do decode, filter, convert, and enrich (including LLM pricing
match). The main thread stays the single database reader: it loads the
pricing registry and broadcasts the compiled model rows to the workers
(re-broadcasting on every reload), so workers never touch the database.
The pure transform is extracted into a dependency-light module (no
Prisma/Redis/ClickHouse imports) so it can run inside a worker.
Importantly, the main thread keeps the existing single consolidated
insert path, so ClickHouse insert batching and part count are unchanged.
The parallelism buys CPU headroom, not more insert streams (which would
add merge pressure).
The worker is bundled as a standalone file at build time and ships in
the existing image with no Dockerfile change. In local load testing the
pool sustained roughly 2.6x the throughput of the single-thread path and
kept the main thread responsive under load.
Once this is merged, oxlint is at a pretty sensible baseline.
**Enable `no-unused-vars`, `typescript/consistent-type-imports`, and
`import/no-duplicates` lint rules**
Turns on three previously-disabled oxlint rules across the monorepo and
fixes all violations:
- **`no-unused-vars`** – enabled as an error with standard ignore
patterns: unused function arguments are ignored by default (`args:
"none"`), variables/caught errors/destructured array elements prefixed
with `_` are allowed, and rest siblings are permitted.
- **`typescript/consistent-type-imports`** – enforced as an error; all
type-only imports now use the `import type` syntax.
- **`import/no-duplicates`** – enforced as an error; duplicate import
statements from the same module have been merged.
The remaining commits clean up the violations found across the codebase:
removing unused variables/imports/type aliases, adding `_` prefixes to
intentionally unused bindings, fixing duplicate imports, and converting
value imports to `import type` where appropriate.
## Summary
This PR improves performance across the Environment Variables page.
## Changes
### Targeted value loading
- load only the non-secret (environmentId, key) pairs required by the
page. Secret values continue to be redacted in the UI.
### SSR windowing + virtualization
- SSR-render only the first 50 rows
- hydrate those rows
- virtualize the remaining dataset client-side
- search is now URL-driven during SSR, ensuring deep links such as
`?search=DATABASE_URL`
### Lightweight 'Create' flow
- 'Create' page no longer loads the full Environment Variables dataset.
## Results
Large projects no longer render thousands of rows during SSR.
Example (~11k rendered rows):
Metric | Before | After
-- | -- | --
Document size | ~150 MB | ~5 MB
SSR rows | ~11k | 50
Browser DOM rows | Thousands | ~26–38
