Wes Mason 76c37ecd24 feat(sdk,core,webapp): offload large batch payloads to object storage (#4165)
## Summary

`batchTrigger` and `batchTriggerAndWait` (and the by-id and by-task
variants) now offload any per-item payload over 128KB to object storage
before sending, the same way single `trigger`/`triggerAndWait` already
do since
[#3785](https://github.com/triggerdotdev/trigger.dev/pull/3785). A batch
of large items no longer inflates the request body past the API limit.

## Demo

A live local run: `batchTriggerAndWait` of 5 items × 300KB (1.5MB
total). Each item offloads to object storage, so the receiver run rows
hold a 65-byte `application/store` pointer instead of the 300KB body,
and every item round-trips (received == sent).

## Design

Both the array and streaming batch paths funnel through
`executeBatchTwoPhase`, so offloading happens once there: each item is
measured, then offloaded through the existing
`conditionallyExportPacket` when it crosses 128KB, with bounded
concurrency so a big batch doesn't fire an unbounded number of presigned
PUTs.

Because items are offloaded before the request, SDK batches arrive as
small `application/store` references, so the server-side inline offload
during item ingest (parallelised in
[#3777](https://github.com/triggerdotdev/trigger.dev/pull/3777)) mostly
no longer fires for them.

Every trigger and item also carries its pre-offload serialised size as
`options.payloadSize`. The trigger span records that value, so an
offloaded payload shows its real size instead of the size of the small
object-store reference (previously the span measured the reference).

Official TypeScript SDK for Trigger.dev

The Trigger.dev SDK is a TypeScript/JavaScript library that allows you to define and trigger tasks in your projects.

About Trigger.dev

Trigger.dev is an open source platform for building and deploying fully-managed AI agents and workflows. Write workflows in normal async TypeScript for everything from simple tasks to long-running AI agents, heavy media processing, complex real-time systems and more. Complete with full observability, managed queues, and elastic infrastructure which handles the horizontal scaling.

Core features

  • Task creation and execution
  • CLI for development and deployment
  • Build system with extensions
  • Management API for runs, schedules, and environment variables

Key Components:

  • Tasks: Background jobs written in TypeScript/JavaScript
  • CLI: Commands for login, init, dev, deploy
  • Build Extensions: Customize builds (Prisma, Python, FFmpeg, etc.)
  • Management API: Programmatic control over runs and resources

Getting started

There are two ways to get started:

  1. Create an account in our web app, create a new project and follow the instructions in the onboarding. Build and deploy your first task in minutes.
  2. Manual setup in your existing project.
