HAQM Elastic File System (HAQM EFS) has increased the maximum number of file locks per NFS mount, enabling customers to use the service for a broader set of workloads that leverage high volumes of simultaneous locks, including message brokers and distributed analytics applications.
HAQM EFS is a serverless, fully elastic file system that makes it easy to set up, scale, and cost-optimize file storage in the AWS Cloud. It can be accessed from any AWS compute service (including HAQM EC2, HAQM EKS, HAQM ECS, and AWS Lambda), and it supports access from up to tens of thousands of compute instances, containers, and function invocations at the same time. Applications spanning multiple compute resources commonly use NFS file locks to manage concurrent updates to individual files. This HAQM EFS update increases the number of simultaneous file locks an NFS mount can acquire to 65,536 (from 8,192 previously), enabling HAQM EFS to be used for a broader set of applications that heavily leverage file locking (including message broker and distributed analytics applications).
The increased per mount lock limits are available for existing and new file systems in all public AWS Regions where HAQM EFS is available with no action required. To learn more, see the HAQM EFS documentation and create a file system using the HAQM EFS Console.
