Re: About naming of VerticallyConcatOperator

We name this as 'VerticallyConcat' before because its logic is opposite of 'vertical table’. But the thing we forgot is that the target of two operations are different: 1. Vertical table: the target of operation is the table needed to split 2. The discussing operator: the target of operation are

About naming of VerticallyConcatOperator

VerticallyConcatOperator is used to horizontally concatenate TsBlocks with the same timestamp column. For example, TsBlock A is: | Time | ColumnA | |1| 1.0| TsBlock B is: | Time | ColumnB | |1| 2.0| After the VerticallyConcatOperator, the result will be: | Time |
