Hi,
when we readstate of of savepooint, we use, "myuid" as a argument of the
function. For example,
DataSet<KeyedState> keyedState = savepoint.readKeyedState("my-uid",
new ReaderFunction());
*Question 1:*
In [1] (line no 79), we get the "uid" with datastream. Then in [2] (line no
45), *how can we use the "uid" that we have got from in [1]?* Because in
[2], there is no declaration of using the "uid" from [1].
*Question 2:*
*what does it mean by "uid" in the datastream of [1]?* is it something a
unique user identification for each stream or for each state of the
datastream?
