New pattern submission - lambda-durable-function-chaining-terraform #2963
Description
To submit a template to the Serverless Patterns Collection, submit an issue with the following information.
IMPORTANT
Patterns are intended to be primarily IaC-focused implementations of 2-4 AWS services, with minimum custom code. They should be commonly used combinations that help developers get started quickly. If you have a utility, demo, or application, submit these to the Serverless Repos Collection instead.
ONLY SUBMIT ONE PATTERN CHANGE PER PR. Multiple patterns or files spanning multiple pattern directories will be automatically rejected.
Patterns may take up to 4-6 weeks to review, test, and merge but there is no SLA and can take significantly longer due to other work the team has.
To learn more about submitting a pattern, read the publishing guidelines page.

THIS PROCESS HAS BEEN SIMPLIFIED. All the information below must be provided in the "example-pattern.json" file cloned from the model **
Note the following information for the model:
-
Description (intro.text) should be a 300-500 word explanation of how the pattern works.
This Terraform pattern demonstrates function chaining using AWS Lambda durable functions. A durable orchestrator invokes three Lambda functions in sequence (add, transform and finalize). The output of each step is passed as the input to the next. The framework automatically checkpoints after every step, so if the orchestrator fails mid-workflow, it replays from the beginning and skips already-completed work. This ensures exactly-once execution without re-processing. -
