Prefect is ideal when you need to manage complex workflows and require fine-grained control over task execution. It excels in scenarios where tasks are dependent on the outputs of previous tasks or when building dynamic pipelines. For example, if you're building a data pipeline that requires conditional logic or needs retry logic for different tasks based on their success or failure, Prefect's orchestration features make this easier to implement than with Meltano.
Meltano is ideal for ETL/ELT projects where you want a cohesive tool that handles all aspects of data workflows without the need for extensive coding or orchestration setup. Use Meltano when you have a simple data integration task and require quick setup and deployment, such as extracting data from a CRM and loading it into a data warehouse for reporting.
