claims-retry 0.1.4

Retry decorator for DynamoDB claim status updates

claims-retry Library

A minimal standalone Python library demonstrating ONE advanced programming construct (a decorator) to make DynamoDB operations more robust via retry with exponential backoff.

Exposed Functions

• update_claim_status(claim_id, new_status): Updates a claim's status with automatic retry on transient throttling errors.

Advanced Construct

• Decorator with_retry(...) wraps a function and transparently retries specific DynamoDB transient error codes using exponential backoff + jitter.

Usage

Set environment variables:

export CLAIMS_TABLE=Claims
export AWS_REGION=eu-west-1

Install (local path example):

pip install -e ./claims_retry_lib

Call:

from claims_retry import update_claim_status, with_retry
update_claim_status("1234-uuid", "APPROVED")
