 - batchfetch: true: pull the result set in batch when executing the query; false: pull the result set row by row. The default value is false. batchfetch uses HTTP for data transfer. The JDBC REST connection supports bulk data pulling function in taos-jdbcdriver-2.0.38 and TDengine 2.4.0.12 and later versions. taos-jdbcdriver and TDengine transfer data via WebSocket connection. Compared with HTTP, WebSocket enables JDBC REST connection to support large data volume querying and improve query performance.
 - charset: specify the charset to parse the string, this parameter is valid only when set batchfetch to true.
 - batchErrorIgnore: true: when executing executeBatch of Statement, if one SQL execution fails in the middle, continue to execute the following SQL. false: no longer execute any statement after the failed SQL. The default value is: false.
+- httpConnectTimeout: REST connection timeout in milliseconds, the default value is 5000 ms.
+- httpSocketTimeout: socket timeout in milliseconds, the default value is 5000 ms. It only takes effect when batchfetch is false.
+- messageWaitTimeout: message transmission timeout in milliseconds, the default value is 3000 ms. It only takes effect when batchfetch is true.
+- useSSL: connecting Securely Using SSL. true: using SSL conneciton, false: not using SSL connection.

 **Note**: Some configuration items (e.g., locale, timezone) do not work in the REST connection.
