Run the Quilt catalog on your machine. Running quilt3 catalog launches a Python webserver on your local machine that serves a catalog web app and provides required backend services using temporary AWS credentials. Temporary credentials are derived from your default AWS credentials (or active AWS_PROFILE) using boto3.sts.get_session_token. For more details about configuring and using AWS credentials in boto3, see the AWS documentation: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/configuration.html

Previewing files in S3

The Quilt catalog allows users to preview files in S3 by downloading and processing/converting them inside the Python webserver running on local machine. Neither your AWS credentials nor data requested goes through any third-party cloud services aside of S3.

config

usage: quilt3 config [-h] [--set KEY=VALUE [KEY=VALUE ...]] [catalog_url]

Configure Quilt

positional arguments:
  catalog_url           URL of catalog to config with, or empty string to

                        not put spaces before or after the = sign). If a value
                        contains spaces, you should define it with double
                        quotes: foo="this is a sentence". Note that values are

Environment variables

QUILT_DISABLE_CACHE

Turn off cache. Defaults to False.

$ export QUILT_DISABLE_CACHE=true

QUILT_DISABLE_USAGE_METRICS

Disable anonymous usage collection. Defaults to False

$ export QUILT_DISABLE_USAGE_METRICS=true

QUILT_MANIFEST_MAX_RECORD_SIZE

Maximum size of a record in package manifest. Setting this variable is strongly discouraged. Defaults to 1_000_000.

QUILT_MINIMIZE_STDOUT

Turn off TQDM progress bars for log files. Defaults to False

$ export QUILT_MINIMIZE_STDOUT=true

QUILT_TRANSFER_MAX_CONCURRENCY

Number of threads for file transfers. Defaults to 10.

This variable could be tried for improving file transfer rate. The optimal value depends on network bandwidth, CPU performance, file sizes, etc.

$ export QUILT_TRANSFER_MAX_CONCURRENCY=20

XDG_*

Quilt uses appdirs for Python to determine where to write data. You can therefore override the following path constants with environment variables using the XDG standard (see appdirs docs).

For instance, AWS Lambda requires the user to use tmp/* as the scratch directory. You can override quilt3.util.CACHE_PATH, so that quilt3 install will succeed in Lambda, by setting the XDG_CACHE_HOME environment variable.
