- batchfetch: true: pulls result sets in batches when executing queries; false: pulls result sets row by row. The default value is: false. batchfetch uses HTTP for data transfer. JDBC REST supports batch pulls. 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.
- httpConnectTimeout: REST connection timeout in milliseconds, the default value is 60000 ms.
- httpSocketTimeout: socket timeout in milliseconds, the default value is 60000 ms. It only takes effect when batchfetch is false.
- messageWaitTimeout: message transmission timeout in milliseconds, the default value is 60000 ms. It only takes effect when batchfetch is true.
- useSSL: connecting Securely Using SSL. true: using SSL connection, false: not using SSL connection.
