**Background**
Runs with `large-1x` or `large-2x` machine presets are disproportionally
affected by scheduling delays during peak times. This is in part caused
by the fact that the worker pool is shared for all runs, meaning large
runs compete with smaller runs for available capacity. Because large runs require
significantly more CPU and memory, they are harder for the scheduler to bin-pack onto existing
nodes, often requiring a node with a significant amount of free resources or
waiting for a new node to spin up entirely. This effect is amplified during peak times
when nodes are already densely packed with smaller workloads, leaving insufficient contiguous resources for large runs.
**Changes**
This PR adds Kubernetes node affinity settings to separate large and standard machine workloads across node pools.
- Controlled via KUBERNETES_LARGE_MACHINE_POOL_LABEL env var (disabled when not set)
- Large machine presets (large-*) get a soft preference to schedule on the large pool, with fallback to standard nodes
- Non-large machines are excluded from the large pool via required anti-affinity
- This ensures the large machine pool is reserved for large workloads while allowing large workloads to spill over to standard nodes if needed
TRQL (pronounced Treacle like the delicious British dark sweet syrup) is
the TRiggerQueryLanguage. It allows users to safely write queries on
their data. The queries are safely turned into ClickHouse queries which
are tenant-safe and not SQL injectable.
https://github.com/user-attachments/assets/bbfca473-b3fc-4150-8fe6-79e8840a2d29
This started out as a translation of HogQL by PostHog from Python to
TypeScript.
Features
- Tenant safe queries.
- Many underlying ClickHouse features including functions and
aggregations.
- Virtual columns, which are exposed to users as real columns but are
actually expressions.
- Transformations of data types and where clauses.
- Simple JSON path querying.
- Limits on execution time.
- Reporting of query statistics.
## Query page
There’s a new Query page (currently behind a feature flag) where you can
write TRQL queries and execute them against your environment, project or
organization.
Features
- Executing TRQL queries
- Syntax highlighting and errors
- Autocomplete
- AI generation/editing of queries
- Help and examples
- Table with auto-inferred data types from the table schema
- Table cell renderers for our special types like Run ids, environments,
machines, tasks, queues, etc.
- Copy/export as CSV/JSON
- Line and bar graphs with grouping and stacking
- History of queries
Replaces `redirectDocument` with `useFetcher` for editing environment
variables. This allows background form submission without full page
reload, which preserves:
- Scroll position in the env vars list
- "Reveal values" toggle state
- Search filter state

Updated the billing alerts documentation to reflect the new spike alerts
feature added in PR #2829. The documentation now explains both standard
alerts (75%, 90%, 100%, 200%, 500%) and spike alerts (10x, 20x, 50x,
100x) that help catch runaway usage from bugs or errors.
## Files changed
- `docs/how-to-reduce-your-spend.mdx` - Added section explaining the two
types of billing alerts

Add colored console warnings when the event loop is blocked and wire
a feature flag to enable/disable notifications- Introduce
notifyEventLoopBlocked() in eventLoopMonitor.server.ts to
log a colored warning with blocked and async type.
- Call notifyEventLoopBlocked() when an event-loop stall is detected.
- Add EVENT_LOOP_MONITOR_NOTIFY_ENABLED to env schema with a default of
"0" so notifications are off by default.
- Will notify when over the `EVENT_LOOP_MONITOR_THRESHOLD_MS` env var
This makes it easier to spot long event-loop stalls during development
or when notifications are explicitly enabled.

This PR fixes some issues with the new BatchQueue by implementing the
full two-phase dequeue process in the FairQueue, and moving the
responsibility of consuming the worker queue to the BatchQueue and
independently enabling it via the `BATCH_QUEUE_WORKER_QUEUE_ENABLED` env
var. We've also introduced the `BATCH_QUEUE_SHARD_COUNT` env var to
control the count of master queue shards in the FairQueue. We can also
control how many queues are considered in each iteration of the master
queue consumer via the `BATCH_QUEUE_MASTER_QUEUE_LIMIT` env var.
This PR will also now skip trying to dequeue from tenants that are at
concurrency capacity, which should lead to fewer issues with low
concurrency tenants blocking higher concurrency tenants from processing.
The Override concurrency limit modal has 2 type="submit" buttons. The
first one in the DOM was firing when the "enter" key is hit which
canceled and reset the limit instead which is a bad UX.
### The fix
This fix adds a hidden button above in the DOM order which mirrors the
Update Override button. Having a double submit button is rare in our
modals so feels safe to add this to the specific modal that needs it.
### Alternative solution
Switching the order of the buttons in the main FormButton component,
then using `flex-row-reverse` to flip them back in CSS works, but it
reverses the tab order. Adding a `tabIndex` to fix that issue didn't
seem to work reliably.
### UI Improvements to the Concurrency page:
- Truncates long branch names and includes a tooltip
- The Tables have a new variant if you don't want the rows to highlight
on hover
- Small fix to pluralize some words in the purchase modal
- Fix to prevent tooltip buttons being `type=submit`
- Updates the /limits docs page to include purchasing more concurrency
- Adds a clear banner when you have a positive balance of unallocated
concurrency
https://github.com/user-attachments/assets/54d927c3-84e3-4d55-8f42-726098f4daf0
- Adds 4 additional alert thresholds to ensure customers are emailed if
they have runaway usage.
- Separated these into a new section called "Spike alerts" with a
tooltip so it's clear what they are.
- Tooltip message is: "Catch runaway usage from bugs or errors. We
recommend keeping these enabled as a safety net."
- A billing service PR now returns all orgs to populate the email list,
rather than oldest 5.
- Adds `defaultChecked` logic to honour existing orgs who have
configured alerts in the DB. New orgs get all alerts checked on by
default.

Adds support for **debounced task runs** - when triggering a task with a
debounce key, subsequent triggers with the same key will reschedule the
existing delayed run instead of creating new runs. This continues until
no new triggers occur within the delay window.
## Usage
```typescript
await myTask.trigger({ userId: "123" }, {
debounce: {
key: "user-123-update",
delay: "5s",
mode: "leading", // default
}
});
```
- **key**: Scoped to the task identifier
- **delay**: How long to wait before executing (supports duration
strings like `"5s"`, `"1m"`)
- **mode**: Either `"leading"` or `"trailing"`. Leading debounce will
use the payload and options from the first run created with the debounce
key. Trailing will use payload and options from the last run.
### "trailing" mode overrides
When using `mode: "trailing"` with debounce, the following options are
updated from the **last** trigger:
- **`payload`** - The task input data
- **`metadata`** - Run metadata
- **`tags`** - Run tags (replaces existing tags)
- **`maxAttempts`** - Maximum retry attempts
- **`maxDuration`** - Maximum compute time
- **`machine`** - Machine preset (cpu/memory)
## Behavior
- **First run wins**: The first trigger creates the run, subsequent
triggers push its execution time later
- **Idempotency keys take precedence**: If both are specified,
idempotency is checked first
- **Max duration**: Configurable via `DEBOUNCE_MAX_DURATION_MS` env var
(default: 10 minutes)
Works with `triggerAndWait` - parent runs correctly block on the
debounced run.
New batch trigger system with larger payloads, streaming ingestion,
larger batch sizes, and a fair processing system.
This PR introduces a new `FairQueue` abstraction inspired by our own
`RunQueue` that enables multi-tenant fair queueing with concurrency
limits. The new `BatchQueue` is built on top of the `FairQueue`, and
handles processing Batch triggers in a fair manner with per-environment
concurrency limits defined per-org. Additionally, there is a global
concurrency limit to prevent the BatchQueue system from creating too
many runs too quickly, which can cause downstream issues.
For this new BatchQueue system we have a completely new batch trigger
creation and ingestion system. Previously this was a single endpoint
with a single JSON body that defined details about the batch as well as
all the items in the batch.
We're introducing a two-phase batch trigger ingestion system. In the
first phase, the BatchTaskRun record is created (and possibly rate
limited). The second phase is another endpoint that accepts an NDJSON
body with each line being a single item/run with payload and options.
At ingestion time all items are added to a queue, in order, and then
processed by the BatchQueue system.
## New batch trigger rate limits
This PR implements a new batch trigger specific rate limit, configured
on the `Organization.batchRateLimitConfig` column, and defaults using
these environment variables:
- `BATCH_RATE_LIMIT_REFILL_RATE` defaults to 10
- `BATCH_RATE_LIMIT_REFILL_INTERVAL` the duration interval, defaults to
`"10s"`
- `BATCH_RATE_LIMIT_MAX` defaults to 1200
This rate limiter is scoped to the environment ID and controls how many
runs can be submitted via batch triggers per interval. The SDK handles
the retrying side.
## Batch queue concurrency limits
The new column `Organization.batchQueueConcurrencyConfig` now defines an
org specific `processingConcurrency` value, with a backup of the env var
`BATCH_CONCURRENCY_LIMIT_DEFAULT` which defaults to 10. This controls
how many batch queue items are processed concurrently per environment.
There is also a global rate limit for the batch queue set via the
`BATCH_QUEUE_GLOBAL_RATE_LIMIT` which defaults to being disabled. If
set, the entire batch queue system won't process more than
`BATCH_QUEUE_GLOBAL_RATE_LIMIT` items per second. This allows
controlling the maximum number of runs created per second via batch
triggers.
## Batch trigger settings
- `STREAMING_BATCH_MAX_ITEMS` controls the maximum number of items in a
single batch
- `STREAMING_BATCH_ITEM_MAXIMUM_SIZE` controls the maximum size of each
item in a batch
- `BATCH_CONCURRENCY_DEFAULT_CONCURRENCY` controls the default
environment concurrency
- `BATCH_QUEUE_DRR_QUANTUM` how many credits each environment gets each
round for the DRR scheduler
- `BATCH_QUEUE_MAX_DEFICIT` the maximum deficit for the DRR scheduler
- `BATCH_QUEUE_CONSUMER_COUNT` how many queue consumers to run
- `BATCH_QUEUE_CONSUMER_INTERVAL_MS` how frequently they poll for items
in the queue
### Configuration Recommendations by Use Case
**High-throughput priority (fairness acceptable at 0.98+):**
```env
BATCH_QUEUE_DRR_QUANTUM=25
BATCH_QUEUE_MAX_DEFICIT=100
BATCH_QUEUE_CONSUMER_COUNT=10
BATCH_QUEUE_CONSUMER_INTERVAL_MS=50
BATCH_CONCURRENCY_DEFAULT_CONCURRENCY=25
```
**Strict fairness priority (throughput can be lower):**
```env
BATCH_QUEUE_DRR_QUANTUM=5
BATCH_QUEUE_MAX_DEFICIT=25
BATCH_QUEUE_CONSUMER_COUNT=3
BATCH_QUEUE_CONSUMER_INTERVAL_MS=100
BATCH_CONCURRENCY_DEFAULT_CONCURRENCY=5
```
## Changelog
- Add disableAdjacentRows prop to TaskRunsTable component to control
table state encoding
- Pass rootOnlyDefault prop from loader to TaskRunsTable for proper
state management
- Disable adjacent run navigation in schedule, waitpoint, and other
inspector views
- Preserve adjacent run navigation on main runs list page with rootOnly
filter support
