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 | ColumnA | ColumnB | | 1 | 1.0 | 2.0 |
Literally, I think it's a horizontal concatenation. So I suggest rename it as HorizontallyConcatOperator. However, I asked the author about the reason for this name. He said, "From the view of a table, adding columns means vertical changes." What's your opinion? +1 for Plan A: Rename it as HorizontallyConcatOperator. +1 for Plan B: Keep current name VerticallyConcatOperator. -- Best, Xiangwei Wei
