若是collect_set 则会去重数组。 还可以利用collect来突破group by的限制,Hive中在group by查询的时候要求出现在select后面的列都必须是出现在group by后面的,即select列必须是作为分组依据的列,但是有的时候我们想根据A进行分组然后随便取出每个分组中的一个B,代入到这个实验中就是按照用户进行分组,然后随便拿出一个...

The docsalso mentionSet-MpPreference -EnableControlledFolderAccess AuditMode, that might prevent the problem, or narrow it down to the event-watching locks being leaked.

g., working set size per processor, and those that define how to execute the workload, e. g., which broadcast method to use. Such parameters clearly affect the resource usage pattern, and through the latter parameters, their work gains a performance tuning aspect. Moreover, a statistical an...
by individually expanding only one pairing error. For such separable error-pairs, we propose to recalculate and collect the rest pairing error to form an error sequence after shifting any one pairing error. Next, by considering every two neighboring errors of the sequence together, a new set of...
Therefore, if you set `--ddl-batch-size` to an excessively large value, the schema size of the tables sent by TiDB in a batch at one time exceeds the specified value, which causes BR to report the `entry too large, the max entry size is 6291456, the size of data is 7690800` ...

This is when we enter a “low phase” in auto-splitting for tables and indexes with a tablet going over tablet_split_low_phase_size_threshold_byte, which is set by default at 512MB, and measured by the size of SST files in the leader tablet peer. The goal is to aggressively distribu...
