Can you also move logic codes into this class from CompactedChangelogFormatReaderFactory? It is better to keep protocol in one single class.

Maybe just create a method isCompactedChangelogPath. And just check it is starting with compacted-changelog-?

[core] Fix checkpoint recovery failure for compacted changelog files
Purpose
Fixes checkpoint recovery failures when using precommit-compact functionality introduced in commit [flink] add coordinate and worker operator for small changelog files compaction (#4380).
Root Cause:
Compacted changelog files have two types of file names:
compacted-changelog-xxx$bid-len.cc-formatcompacted-changelog-xxx$bid-len-off-len2.cc-formatFake file names point to segments of real files but don't exist in the filesystem. The
checkFilesExistencemethod was directly checking these fake file paths, causing recovery failures.Solution:
CompactedChangelogPathResolverutility class to resolve fake file paths to real file pathsTableCommitImpl.checkFilesExistence()to resolve all paths before checking existencexxx$bid-len.cc-format): return original pathxxx$bid-len-off-len2.cc-format): resolve tobucket-bid/xxx$bid-len.cc-formatTests
CompactedChangelogPathResolverTestto verify path resolution logicAPI and Format
No changes to public API or storage format. This is an internal fix for file path resolution.
Documentation
No new features introduced. This is a bug fix for existing precommit-compact functionality.
