> Hi Raghu:
> Yep, you are right, so I said solution 1 is not very precise when there
> are still some data you want to update/delete being stored in stream
> segments, solution 2 can handle this scenario you mentioned.
> But, in my opinion, the scenario of deleting historical data is more
> common than the one of updating data, the data size of stream table will
> grow day by day, user generally want to delete specific data to make data
> size not too large, for example, if user want to keep data for one year,
> he
> need to delete one year ago of data everyday. On the other hand, solution
> 2
> is more complicated than solution 1, we need to consider the implement of
> solution 2 in depth.
> Based on the above reasons, Liang Chen, Jacky, David and I prefered to
> implement Solution 1 first. Is it ok for you?
>
> Is there any other suggestion?
