| split.string_split_mode | String | No | sample
| Supports different string splitting algorithms. By default, `sample` is
used to determine the split by sampling the string value. You can switch to
`charset_based` to enable charset-based string splitting algorithm. When set to
`charset_based`, the algorithm assumes characters of partition_column are
within ASCII range 32-126, which covers most character-based splitting
scenarios.

| split.string_split_mode_collate | String | No | -
| Specifies the collation to use when string_split_mode is set to
`charset_based` and the table has a special collation. If not specified, the
database's default collation will be used.

+### Table Matching
+
+The JDBC Source connector supports two ways to specify tables:
+
+1. **Exact Table Path**: Use `table_path` to specify a single table with its
full path.
+ ```hocon
+ table_path = "testdb.table1"
+ ```
+
+2. **Regular Expression**: Use `table_path` with a regex pattern to match
multiple tables.
+ ```hocon
+ table_path = "testdb.table\\d+" # Matches table1, table2, table3, etc.
+ ```
+
+#### Regular Expression Support
+
+The JDBC Source connector supports regular expressions for table matching.
This is useful when you want to read multiple tables that follow a specific
naming pattern.
+
+Examples:
+- `testdb.table+` - Matches all tables starting with "table" followed by
numbers
+- `testdb.*` - Matches all tables in the `testdb` database
Review Comment:
The regular expression testdb.* will only match all the tables in the testdb
database and will not match the testdb2 database.
