# Settings

You can control workflow-specific settings in the Settings header, just above your workflow's code.

Workflow settings

# Errors

By default, any errors raised in a workflow are sent to your registered email address. You'll receive an email with the details of the error, once per error, per workflow, per 24-hour period.

# Execution Controls

# Execution Timeout Limit

Workflows have a default execution limit, which defines the time workflows can run for a single invocation until they're timed out.

If your workflow times out, and needs to run for longer than the default limit, you can change that limit here.

# Memory

By default, workflows run with 256MB of memory. If you're processing a lot of data in memory, you might need to raise that limit. Here, you can increase the memory of your workflow up to 10GB.

Pipedream charges invocations proportional to your memory configuration. When you modify your memory settings, Pipedream will show you the number of invocations you'll be charged per execution. Read more here.

# Concurrency and Throttling

Manage the concurrency and rate at which events from a source trigger your workflow code.

# Attachments

Sometimes, you'll need to reference static files in your workflow, like a CSV. Files uploaded in the Attachments section can be referenced in your workflow using the $attachments object.

For example, if you upload a file named test.csv, Pipedream will expose the file path of the uploaded file at $attachments["test.csv"]. You can read the contents of the file using fs.readFileSync:

import fs from "fs";

const fileData = fs.readFileSync($attachments["test.csv"]).toString();
File attachment data

# Limits

Each attachment is limited to 10MB in size. The total size of all attachments within a single workflow cannot exceed 200MB.
