Description:The `xpack-amzn` plugin extends Nextflow's AWS Batch executor with enhanced storage and security capabilities, adding support for Amazon EFS, POSIX-compatible file systems (FSx for Lustre, Qumulo, Weka), and AWS Secrets Manager integration. It solves the problem of managing shared file systems and credentials securely in cloud-based bioinformatics pipelines. This plugin is used by researchers and data scientists running computationally intensive Nextflow workflows on AWS who need reliable, scalable storage and credential management.
