+### Table Matching With Regex
+
+The Kudu Source supports using regular expressions on `table_name` to match multiple tables (including whole-database style synchronization, since Kudu tables are in a single logical database).
+
+#### Exact Table Name
+
+Use `table_name` to specify a single Kudu table with an exact name:
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    table_name = "kudu_source_table_1"
+  }
+}
+```
+
+#### Regex Matching
+
+Use `table_name` as a regex pattern and enable `use_regex` to read multiple tables with one configuration:
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    # Match tables like kudu_source_table_1, kudu_source_table_2, etc.
+    table_name = "kudu_source_table_\\d+"
+    use_regex = true
+  }
+}
+```
+
+You can also combine regex entries in `table_list`:
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    table_list = [
+      {
+        table_name = "kudu_source_table_1"
+      },
+      {
+        table_name = "kudu_source_table_2"
+      },
+      {
+        # Regex matching - any table whose name starts with prefix_ and ends with digits
+        table_name = "prefix_\\d+"
+        use_regex = true
+      }
+    ]
+  }
+}
+```
+
+#### Whole-Database Matching
+
+You can also synchronize all tables in the current Kudu cluster (or all business tables in the current instance, if there are no system tables) by using a catch-all regex:
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    # Match all tables in the current Kudu cluster
+    table_name = ".*"
+    use_regex = true
+  }
+}
+```

+### 使用正则表达式匹配表
+
+Kudu Source 支持在 `table_name` 上使用正则表达式来匹配多张表（由于 Kudu 逻辑上只有一个 database，因此也可以用来实现“整库表”同步）。
+
+#### 精确表名
+
+使用 `table_name` 指定单个 Kudu 表的精确名称：
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    table_name = "kudu_source_table_1"
+  }
+}
+```
+
+#### 正则匹配
+
+将 `table_name` 视为正则表达式，并开启 `use_regex`，即可用一条配置匹配多张表：
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    # 匹配 kudu_source_table_1、kudu_source_table_2 等
+    table_name = "kudu_source_table_\\d+"
+    use_regex = true
+  }
+}
+```
+
+也可以在 `table_list` 中组合精确表和正则表：
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    table_list = [
+      {
+        table_name = "kudu_source_table_1"
+      },
+      {
+        table_name = "kudu_source_table_2"
+      },
+      {
+        # 使用正则匹配，以 prefix_ 开头、以数字结尾的所有表
+        table_name = "prefix_\\d+"
+        use_regex = true
+      }
+    ]
+  }
+}
+```
+
+#### 整库匹配
+
+如果当前 Kudu 实例中只有业务表，或者你希望“一次性同步所有表”，可以使用一个全匹配的正则：
+
+```hocon
+source {
+  kudu {
+    kudu_masters = "kudu-master:7051"
+    # 匹配当前 Kudu 实例中的所有表
+    table_name = ".*"
+    use_regex = true
+  }
+}
+```
