lei w updated HUDI-4613:
------------------------
Description:
When the number of logFile files exceeds a certain amount of data, the
construction of fsview will become very time-consuming. The reason is that the
LogFileComparator#compare method is frequently called when constructing a
filegroup, and regular expressions are used in this method.

INFO view.AbstractTableFileSystemView: addFilesToView: NumFiles=60801,
NumFileGroups=200, FileGroupsCreationTime=34036, StoreTimeTaken=2
