Description
Currently Hudi follows a model of having a static target file size configured by the user.
We should consider a mode where Hudi will automatically configure the file-size based on the expected target table size, similar to what [Delta does|https://learn.microsoft.com/en-us/azure/databricks/delta/tune-file-size] for ex.

Research direction
No source files, tests, or entry points are named. Start by reviewing JIRA HUDI-5494, the linked Delta file-size guidance, and the Hudi-3249 epic; done means Hudi can derive target file size from the expected target table size instead of requiring only a static user setting.
