# Fluss Flink Tiering
-This module contains one class FlussLakeTiering.
+This module provides the infrastructure for tiering Fluss data to lake formats
(e.g., Apache Paimon),
+consisting of FlussLakeTiering which encapsulates the core configuration and
job graph logic,
+and FlussLakeTieringEntrypoint which serves as the official Flink job main
class and entrypoint.
The reason for extracting it as a separate module is that: When executing the
Flink jar job, a jar must be specified.
If a `fluss-flink.jar` is specified, it may cause various classloader issues,
as there are also `fluss-flink.jar`
