Key Questions Answered
How does Prodicle Distribution handle document watermarking?
Prodicle Distribution creates unique watermarked documents for each recipient based on the distribution job. For instance, if there are 10 files and 20 recipients, it generates 200 unique watermarked documents or links, ensuring secure delivery of sensitive content.
What improvements were made to Prodicle Distribution after migrating to Cosmos?
After migrating to Cosmos, Prodicle Distribution experienced a 10x growth in adoption, supporting hundreds of productions and millions of watermarks monthly. The migration improved observability, reduced support tickets, and enhanced the ability to debug workflows effectively.
Why is observability crucial in asynchronous workflows?
Observability is essential in asynchronous workflows to effectively debug and trace issues across multiple systems. It allows teams to visualize the state of workflows, making it easier to identify bottlenecks and resolve errors quickly.

This reflects the scale of operations after migrating to Cosmos.
Technologies & Tools
Workflow Orchestrator
Cosmos
Used for managing asynchronous workflows and improving observability.
Observability Tool
Nirvana
Utilized for debugging workflows and identifying bottlenecks.
Key Actionable Insights
1Implement a centralized observability tool like Nirvana to enhance debugging capabilities.Centralizing observability allows engineers to visualize workflows and logs in one place, making it easier to identify and resolve issues quickly, especially during high-pressure situations.
2Consider migrating to a workflow orchestrator like Cosmos for better performance and scalability.Using Cosmos can help manage asynchronous tasks more effectively, reducing latency and improving the overall system's responsiveness to bursty traffic demands.
3Adopt a modular approach to asynchronous workflows to improve maintainability.By breaking down workflows into smaller, manageable components, teams can focus on specific areas of the system, making it easier to implement changes and add new features without overwhelming the existing architecture.
Common Pitfalls
1
Failing to integrate observability tools can lead to difficulties in debugging asynchronous workflows.
Without proper observability, engineers may struggle to trace issues across multiple systems, leading to increased downtime and frustration during critical incidents.
2
Neglecting to manage bursty traffic can overwhelm the system and lead to performance degradation.
If systems are not designed to handle sudden spikes in traffic, it can result in slow processing times and failed document deliveries, impacting user experience.
