Try manually executing stream load to import 15,000 columns. Let’s see if it’s a flink problem or a stream load problem. |

How long is the checkpoint, the time imported in flink is related to the checkpoint time? |

font{
line-height: 1.6;
}
ul,ol{
padding-left: 20px;
list-style-position: inside;

改用新版本的flink-doris-connector后,暂时没发现问题

场景:
需要实时写入,一条数据将会stream load为doris表中有15000个字段的一行。
测试环境下,开启2PC。当有20条数据在一次checkpoint时做stream load时,checkpoint耗时13s,超过容忍阈值。
一条数据不大,不会超过1M,猜测为字段过多导致的插入慢。
提问:
1.确认doris是否支持这么多列的快速插入?
2.如果doris支持,那么该如何优化插入速度?
