What are some common challenges faced in implementing monitoring and alerting systems for complex data pipelines?

Implementing monitoring and alerting systems for complex data pipelines presents several challenges. Ensuring end-to-end visibility involves tracking data flow from source to destination, which becomes complex in pipelines with multiple stages and transformations. Handling large volumes of data requires scalable solutions capable of processing and analyzing massive datasets efficiently. Dealing with diverse data sources involves integrating and harmonizing data from various formats and platforms. Managing real-time processing requires monitoring tools capable of detecting and responding to issues in real-time to maintain pipeline performance and data integrity.
