+> Parallelizer provides a tool for implementing a **task queue** using SQS and DynamoDB. It is up to the consumer to implement **task ordering** and **test grouping** by themselves.

 ## Basic concepts
 
 A **Parallelizer Job** is a collection of _Parallelizer Tasks._ Each parallelizer job has a unique ID, which will be used as the queue ID in SQS. This ID can be reused when retrying a job. This allows completed tasks to be skipped and only the failed tasks to be retried.
