| password | Yes | NONE | The password of the preceding account. |
| sink.semantic | No | at-least-once | The semantic guaranteed by sink. Valid values: **at-least-once** and **exactly-once**. |
| sink.version | No | AUTO | The interface used to load data. This parameter is supported from Flink connector version 1.2.4 onwards. <ul><li>`V1`: Use [Stream Load](https://docs.starrocks.io/en-us/latest/loading/StreamLoad) interface to load data. Connectors before 1.2.4 only support this mode. </li> <li>`V2`: Use [Transaction Stream Load](https://docs.starrocks.io/en-us/latest/loading/Stream_Load_transaction_interface) interface to load data. It requires StarRocks to be at least version 2.4. Recommends `V2` because it optimizes the memory usage and provides a more stable exactly-once implementation. </li> <li>`AUTO`: If the version of StarRocks supports transaction Stream Load, will choose `V2` automatically, otherwise choose `V1` </li></ul> |
| sink.label-prefix | No | NONE | The label prefix used by Stream Load. Recommend to configure it if you are using exactly-once with connector 1.2.8 and later. See [exactly-once usage notes](#exactly-once). |
| sink.label-prefix | No | flink | The label prefix used by Stream Load. Recommend to configure it if you are using exactly-once with connector 1.2.8 and later. See [exactly-once usage notes](#exactly-once). |
| sink.buffer-flush.max-bytes | No | 94371840(90M) | The maximum size of data that can be accumulated in memory before being sent to StarRocks at a time. The maximum value ranges from 64 MB to 10 GB. Setting this parameter to a larger value can improve loading performance but may increase loading latency. This parameter only takes effect when `sink.semantic` is set to `at-least-once`. If `sink.semantic` is set to `exactly-once`, the data in memory is flushed when a Flink checkpoint is triggered. In this circumstance, this parameter does not take effect. |
| sink.buffer-flush.max-rows | No | 500000 | The maximum number of rows that can be accumulated in memory before being sent to StarRocks at a time. This parameter is available only when `sink.version` is `V1` and `sink.semantic` is `at-least-once`. Valid values: 64000 to 5000000. |
| sink.buffer-flush.interval-ms | No | 300000 | The interval at which data is flushed. This parameter is available only when `sink.semantic` is `at-least-once`. Valid values: 1000 to 3600000. Unit: ms. |
