Method Details

getDirectS3Read

@Stability(Stable)
@Nullable
default String getDirectS3Read()

Specifies if a function reads from the file system for the lowest latency, or through Amazon S3 Files feature "direct Amazon S3 bucket reads" for the highest throughput.

Valid values:

• AUTO (default) – Direct reads are active for functions you configure with 512 MB or more of memory.
• ENABLED – Enforces all reads are directly from the Amazon S3 bucket, regardless of available memory (less than 512 MB).
• DISABLED – Routes all reads through the file system, regardless of memory configuration.

To use direct reads, you must grant the execution role the s3:GetObject and s3:GetObjectVersion permissions. If a direct read fails, Lambda automatically falls back to reading through the file system.
