Limitation: Snapshot Processing Snapshot functionality will NOT be available in the real-time system as HDFS inotify does not provide snapshot-related events & nodeId. The system focuses exclusively on regular file system operations (fsimage processing).

Limitation: Non-HDFS Operations Permission changes or file system operations performed outside standard HDFS APIs (i.e., not executed via HDFS commands or NameNode-backed interfaces) will not generate inotify events and will not be captured in real time. Such changes will only be reflected during subsequent fsimage processing.
