What happened

sql模式 ，starrocks写入时，当stream load 报错502错误，整个任务仍然是执行成功的，写入统计指标也是错误的统计了未真正写入成功的记录数，其实数据库里并未写入数据，但是统计指标却统计了记录。

How to reproduce

模拟 stream load url 报 502，

首先可以启动一个spring-boot RestController

@RequestMapping("/api/databaseName/tableName/_stream_load")
    public ResponseEntity<String> api(@RequestHeader Map<String, String> headers, @RequestBody byte[] data) {
        Map<String, Object> result = new HashMap<>();
        System.out.println();
        System.out.println("==============================================");
        headers.forEach((key, value) -> {
            // 日志中输出所有请求头
            System.out.println(String.format("Header '%s' = %s", key, value));
        });

        String receivedData = new String(data);
        System.out.println("Received data: " + receivedData);
        return new ResponseEntity<>("Resource not found", HttpStatus.BAD_GATEWAY);
    }

然后在chunjun StarRocksStreamLoadVisitor.java 文件里修改如上：

private Map<String, Object> doHttpPut(
            String loadUrl, String label, byte[] data, String httpHeadColumns) throws IOException {
        log.info(
                String.format(
                        "Executing stream load to: '%s', size: '%s', thread: %d",
                        loadUrl, data.length, Thread.currentThread().getId()));
       // 增加将正确的stream load url 修改成上方能报502错误的url地址
        loadUrl = loadUrl.replace("xxxx", "127.0.0.1:8080");

测试sql：

CREATE TABLE source
(
    `id`    bigint,
    `username`  string,
    `age`   int
) with (
      'connector' = 'stream-x',
      'number-of-rows' = '2000'
);

CREATE TABLE sink
(
    `id`    bigint,
    `username`  string,
    `age`   int
) with (
      'connector' = 'starrocks-x',
      'url' = 'jdbc:mysql://x.x.x.x:9030/test?useUnicode=true&characterEncoding=utf8&useSSL=false&rewriteBatchedStatements=true&&serverTimezone=Asia/Shanghai',
      'fe-nodes' = 'x.x.x.x:8030',
      'schema-name' = 'test',
      'table-name' = 'test_aaa',
      'username' = 'xxx',
      'password' = 'xxx'
      );

insert into sink select * from source;
