Amazon Lambda customers in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD, can configure up to 10,240 MB of ephemeral storage for their Lambda functions, a 20x increase compared to the previous limit of 512 MB.

With this release, you can now control the amount of ephemeral storage a function gets for reading or writing data, allowing you to use Amazon Lambda for ETL jobs, ML inference, or other data-intensive workloads. You can configure ephemeral storage (/tmp) between 512 MB and 10,240 MB. You can set this in the Amazon Web Services Management Console, Amazon Web Services CLI, or Amazon Web Services SDKAmazon Serverless Application ModelAmazon Lambda API, and Amazon CloudFormation. With 10 GB container image support, 10 GB function memory, and 10 GB of ephemeral function storage, you can support workloads such as using large temporal files, data and media processing, machine learning inference, and financial analysis.

You can continue to use up to 512 MB for free and are charged for the amount of storage you configure over the free limit for the duration of invokes. For more details on pricing and regional availability, visit Amazon Lambda product and pricing page.
