What is the maximum buffer size for in-memory repeatable streams in Mule 4?

In Mule 4, the maximum buffer size for in-memory repeatable streams is indeed limited to the application's memory. This means that the actual size can vary based on the available memory allocated to the Mule application, which could be significantly more than any fixed limit defined by the options given.

The concept of in-memory repeatable streams allows for better performance and data processing capabilities as they minimize the need to read data from external sources repeatedly. The ability to utilize the application's memory for buffering enhances the efficiency of processing streams of data, which is particularly relevant in data-heavy operations and integrations.

Thus, while you might see numbers like 100, 250, or 500 objects in other contexts, they do not accurately represent the maximum limit for this specific case in Mule 4. Instead, the flexibility granted by the application's memory allows for scalable processing based on the actual workload and available resources.
