Can the 1MB request payload limit for an ALB Lambda target be increased?

Question

According to documentation, when using a Lambda target with ALB "The maximum size of the request body that you can send to a Lambda function is 1 MB." https://docs.aws.amazon.com/elasticloadbalancing/latest/application/lambda-functions.html

According to [Lambda documentation](https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-limits.html) the maximum synchronous invocation payload is 6MB.

Is the 1MB maximum request body size for a Lambda target in ALB a hard limit or can it be raised if a customer use case warrants it?

Accepted Answer

The 1MB max size for the request body cannot be changed.

Also do note the header limits for ALBs which are also hard lmits:

HTTP/1.x headers

Request line: 16 K

Single header: 16 K

Whole header: 64 K

HTTP/2 headers

Request line: 8 K

Single header: 8 K

Whole header: 64 K
