发帖数: 1269 | 1 I got the following problem, and want to know an efficient solution.
Data flows as streams (record with a value and a timestamp).
How can I efficiently check if there is a duplicate in a time window T?
Thanks a lot. | r******h
发帖数: 809 | 2 Do you mean duplicate in the window or duplicate in the whole streaming,
with accessing data only in a window each time?
And do you expect an exact result or approximate result?
