 Incremental Clustering supports:
-- Support incremental clustering; minimizing write amplification as possible.
-- Support small-file compaction; during rewrites, respect target-file-size.
-- Support changing clustering keys; newly ingested data is clustered according to the latest clustering keys.
-- Provide a full mode; when selected, the entire dataset will be reclustered.

+**Note**: If data ordering within bucketed tables is not a concern, you can set `'bucket-append-ordered'` to `false` 
+to disable this ordering requirement. This allows you to enable Incremental Clustering for bucketed tables,

 Once Incremental Clustering for a table is enabled, you can run Incremental Clustering in batch mode periodically 
 to continuously optimizes data layout of the table and deliver better query performance.
