【已解决】2.1版本，物化视图使用 hll_union 导致routine load 报错

Viewed 135
mtmv 2.1

创建一个聚合表，包含HLL列用于算大概的排重数，而后从kafka中通过 routine load 方式导入数据。在没有创建物化视图时，一切工作正常，查询也正常。用物化视图进行查询加速后，routine load报错。


但是创建物化视图加速 hll_union_agg后，routine load 报错

物化视图中是否支持：hll_union，如果支持，我这个应该怎么修复呢。

PS. 单分区按照设备id为key做聚合表，预计数据会有20亿行数据。可以使用hll_hash(设备id)来做大概的排重数统计吧

2.1.3 已fix ：https://github.com/apache/doris/pull/33373

升级到2.1.1完成后，问题并没有解决

保留 conf/be.conf后，直接用2.1.1的文件进行启动。确认版本升级完成
