+### Supported ClickHouse Table Engine Types.
+
+The sink connector supports the following ClickHouse Engine types:
+- **ReplacingMergeTree**: See [Architecture] (doc/mutable_data.md) for more information.
+    - ReplacingMergeTree is a variant of MergeTree that allows for updates and deletes.
+    - It is the default engine type used with the sink connector when tables are auto created using
+    - `auto.create.tables` set to `true`.
+- **ReplicatedReplacingMergeTree**:
+    - ReplicatedReplacingMergeTree is a variant of ReplicatedMergeTree that allows for updates and deletes.
+    - To enable this engine type, set the `"auto.create.tables.replicated` to `true`, sink connector will
+      create tables with this engine type.
