 ## Batch Read
 
+### Full Scan of Primary Key Tables
+
+Fluss can perform a bounded full-table scan on a primary-key table directly 
via the server-side KV scan API.
+
+Enable the feature by setting `client.scanner.kv.server-side.enabled = true` 
on the table or as a SQL hint:
+
+- This is a **bounded** read. The source finishes once all buckets have been 
drained and does not continue reading the change-log.
+- On task restart, each bucket is rescanned from scratch. Progress within a 
scan session is not checkpointed, because an expired or invalidated server-side 
session cannot be resumed from a mid-point.

Review Comment:
   On task restart, each bucket is scanned again from the beginning. Progress 
within an active scan session is not checkpointed because expired or 
invalidated server-side sessions cannot be resumed from an intermediate 
position.
