User guide
Fusion is a virtual, lightweight, distributed file system designed to optimize the data access of Nextflow data pipelines.
Fusion enables seamless filesystem I/O to cloud object stores via a standard POSIX interface resulting in simpler pipeline logic and faster, more efficient pipeline execution.
Fusion requires a license for use in Seqera Platform compute environments or directly in Nextflow. See Fusion licensing for more information.
Getting started
Fusion smoothly integrates with Nextflow and does not require any installation or change in pipeline code. It only requires to use of container runtime or a container computing service such as Kubernetes, AWS Batch, or Google Cloud Batch.
This feature requires Nextflow 22.10.0 or later.
Nextflow installation
If you have already installed Nextflow, update to the latest version using this command:
nextflow -self-update
If you don't have Nextflow already installed, install it with the command below:
curl get.nextflow.io | bash
Fusion configuration
To enable Fusion in your Nextflow pipeline add the following snippet to your nextflow.config file:
fusion.enabled = true
wave.enabled = true
tower.accessToken = '<PLATFORM_ACCESS_TOKEN>'
Replace <PLATFORM_ACCESS_TOKEN> with your Platform access token.
