Alan Gates commented on PIG-1426:
---------------------------------
It will affect Zebra and BinStorage, because it changes the Tuple.readFields()
function, which both of them use to decode the data.
> Change the size of Tuple from Int to VInt when Serialize Tuple

> Most of time, the size of tuple is not very large, one byte is enough for
> store the size of tuple. So I suggest to use VInt instead of Int for the size
> of tuple when doing Serialization. Because the key type of map output is
> Tuple, so this can reduce the amount of data transferred from mapper to
> reducer.
