---------------------------
Summary: Avoid the use of regular expressions when call
hoodieFileGroup#addLogFile function
Key: HUDI-4613
URL: https://issues.apache.org/jira/browse/HUDI-4613
Project: Apache Hudi
Issue Type: Improvement
Components: compaction
Reporter: lei w
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.
