实时数仓 Hologres分区的相关内容

Hologres是不是就即使这个分区表里没数据，我也得把这个分区表删了才有效果？

DataWorks中hologres节点里，表名要拼接分区，表名后面怎么插入参数呢？

DataWorks中hologres节点里，表名要拼接分区，表名后面怎么插入参数呢？用 tableA_'${dataPart}'好像不行

[帮助文档] 通过DataWorks的for-each节点操作Hologres的多个分区子表

当您需要对Hologres中分区父表的多个分区子表进行操作（例如执行INSERT、DELETE或UPDATE）时，可以通过DataWorks的for-each节点的循环遍历功能实现，简化复杂的循环处理逻辑，数据更新成功后即可在父表中查看所有分区数据。

Hologres子表表名满足就会被纳入到分区管理系统里面，其实是跟分区值没关系？

Hologres子表表名满足{parenttable}{time_suffix}就会被纳入到分区管理系统(定时删除分区，转换冷热数据)里面，其实是跟分区值没关系？比如create table tbl2_20230808 partition of tbl2 for values in('2023-0...

Hologres的动态分区日期格式能不能自定义，我这边是使用YYYY-MM-DD的？

Hologres有没办法直接插入到分区父表，使用插入的一个数据列作为分区，分区不存在自动创建？

Hologres扫描6个分区（6个分区数据量大概是1.5亿条），还有优化空间吗？

Hologres扫描6个分区（6个分区数据量大概是1.5亿条），只查 count(distinct user_id) 的话，查询时间2秒左右，还有优化空间吗？

Hologres使用动态分区管理，通过主键+segment_key时间范围查询性能变差，是什么原因？

Hologres使用动态分区管理，按日期分区之后，通过主键+segment_key时间范围查询性能变差，是什么原因？

Hologres holostudio为什么不支持max_pt('table')取最大分区这个方法?

Hologres holostudio为什么不支持max_pt('table')取最大分区这个方法?好像在HoloStudio报错是max_pt不是关键词，我写的时候它确实没有颜色改变，但是切换MaxCompute里确实是关键词，会改变颜色

目前看了hologres好像写入不支持分区自动路由功能吧？

请问你们这个也能够实现分区写入自动路由功能嘛。目前看了hologres好像写入不支持分区自动路由功能吧？
