## Summary Prisma expands `in` / `notIn` into one bind parameter per element, so every distinct list length is a separate prepared statement. Where the length tracks data volume (a batch size, a run-graph fan-out, a prior query's id set) one call site can mint hundreds of them. Each is used about once, but inserting it evicts an entry that was being reused, so the cost lands on unrelated queries sharing the pooler's statement cache. An unbounded list also risks the 65535 bind-parameter ceiling. `boundedIn()` pads a filter list to the next power of two by repeating its last element. `IN` and `NOT IN` ignore duplicates, so results are unchanged, and a call site drops from one statement per length to at most `log2(cap)`. Applied to all existing sites. ## Enforcement Two oxlint rules require the helper: a list filter must be an inline array literal or a `boundedIn()` call. - The first covers filters reached through `where` / `having` / `cursor`, and deliberately never descends into `data`, `create`, `update`, `set` or `equals`. A key named `in` in those positions is user data, not a predicate, and rewriting it would corrupt what gets stored or compared. - The second covers bare filter objects passed to where-building helpers, which the first cannot see. It found five sites in the run-graph batch loaders that were otherwise invisible. Both rules follow filters through the shapes they are actually written in: conditional expressions, logical-and objects, spread-conditional properties, computed keys, and call arguments. An array literal only counts as fixed-arity when nothing spreads into it, since `[...new Set(ids)]` has a runtime length. Twelve sites were hidden behind those shapes until the rules handled them. Scoped to `in` and `notIn`. The scalar-list filters `hasSome` and `hasEvery` compile to `&& $1` and `@> $1`, passing the whole array as a single bind parameter, so their arity never reaches the statement text and there is nothing to bound. Both rules are `error`, so new call sites fail CI. That ratchet has already caught four sites added by other PRs while this one was in review. ## Notes `boundedIn` pads by repeating rather than with null: `x NOT IN (a, b, NULL)` is never true, so null-padding a `notIn` filter would silently return no rows. Lists above 32768 are returned unchanged so padding can never push a query past the parameter limit. Route modules reach the helper through `~/db.server` rather than importing the database barrel directly, since a value import of that barrel into a module that also exports a React component is only safe while dead-code elimination prunes it. Measured on a local rig: 300 distinct list lengths produce 300 prepared statements unpadded, 10 padded. Verified end-to-end against a local stack with the full task-suite sweep, which surfaced no regressions.

About Trigger.dev
Trigger.dev is the open-source platform for building AI workflows in TypeScript. Long-running tasks with retries, queues, observability, and elastic scaling.
The platform designed for building AI agents
Build AI agents using all the frameworks, services and LLMs you're used to, deploy them to Trigger.dev and get durable, long-running tasks with retries, queues, observability, and elastic scaling out of the box.
-
Long-running without timeouts: Execute your tasks with absolutely no timeouts, unlike AWS Lambda, Vercel, and other serverless platforms.
-
Durability, retries & queues: Build rock solid agents and AI applications using our durable tasks, retries, queues and idempotency.
-
True runtime freedom: Customize your deployed tasks with system packages – run browsers, Python scripts, FFmpeg and more.
-
Human-in-the-loop: Programmatically pause your tasks until a human can approve, reject or give feedback.
-
Realtime apps & streaming: Move your background jobs to the foreground by subscribing to runs or streaming AI responses to your app.
-
Observability & monitoring: Each run has full tracing and logs. Configure error alerts to catch bugs fast.
Key features:
- JavaScript and TypeScript SDK - Build background tasks using familiar programming models
- Long-running tasks - Handle resource-heavy tasks without timeouts
- Durable cron schedules - Create and attach recurring schedules of up to a year
- Trigger.dev Realtime - Trigger, subscribe to, and get real-time updates for runs, with LLM streaming support
- Build extensions - Hook directly into the build system and customize the build process. Run Python scripts, FFmpeg, browsers, and more.
- React hooks - Interact with the Trigger.dev API on your frontend using our React hooks package
- Batch triggering - Use batchTrigger() to initiate multiple runs of a task with custom payloads and options
- Structured inputs / outputs - Define precise data schemas for your tasks with runtime payload validation
- Waits - Add waits to your tasks to pause execution for a specified duration
- Preview branches - Create isolated environments for testing and development. Integrates with Vercel and git workflows
- Waitpoints - Add human-in-the-loop judgment at critical decision points without disrupting workflow
- Concurrency & queues - Set concurrency rules to manage how multiple tasks execute
- Multiple environments - Support for DEV, PREVIEW, STAGING, and PROD environments
- No infrastructure to manage - Auto-scaling infrastructure that eliminates timeouts and server management
- Automatic retries - If your task encounters an uncaught error, we automatically attempt to run it again
- Checkpointing - Tasks are inherently durable, thanks to our checkpointing feature
- Versioning - Atomic versioning allows you to deploy new versions without affecting running tasks
- Machines - Configure the number of vCPUs and GBs of RAM you want the task to use
- Observability & monitoring - Monitor every aspect of your tasks' performance with comprehensive logging and visualization tools
- Logging & tracing - Comprehensive logging and tracing for all your tasks
- Tags - Attach up to ten tags to each run, allowing you to filter via the dashboard, realtime, and the SDK
- Run metadata - Attach metadata to runs which updates as the run progresses and is available to use in your frontend for live updates
- Bulk actions - Perform actions on multiple runs simultaneously, including replaying and cancelling
- Real-time alerts - Choose your preferred notification method for run failures and deployments
Write tasks in your codebase
Create tasks where they belong: in your codebase. Version control, localhost, test and review like you're already used to.
import { task } from "@trigger.dev/sdk";
//1. You need to export each task
export const helloWorld = task({
//2. Use a unique id for each task
id: "hello-world",
//3. The run function is the main function of the task
run: async (payload: { message: string }) => {
//4. You can write code that runs for a long time here, there are no timeouts
console.log(payload.message);
},
});
Deployment
Use our SDK to write tasks in your codebase. There's no infrastructure to manage, your tasks automatically scale and connect to our cloud. Or you can always self-host.
Environments
We support Development, Staging, Preview, and Production environments, allowing you to test your tasks before deploying them to production.
Full visibility of every job run
View every task in every run so you can tell exactly what happened. We provide a full trace view of every task run so you can see what happened at every step.
Getting started
The quickest way to get started is to create an account and project in our web app, and follow the instructions in the onboarding. Build and deploy your first task in minutes.
