Jeff Zhang commented on PIG-1426: --------------------------------- Alan, I look at your comments again. seems you are considering the same problem. In the case, I'd like to introduce another type of Tuple and TupleFactory to keep the incompatibility. The zebra still use the Int type tuple, and the pig core use the VInt type tuple. What do you think ? > Change the size of Tuple from Int to VInt when Serialize Tuple > -------------------------------------------------------------- > > Key: PIG-1426 > URL: https://issues.apache.org/jira/browse/PIG-1426 > Project: Pig > Issue Type: Improvement > Components: data > Affects Versions: 0.8.0 > Reporter: Jeff Zhang > Assignee: Jeff Zhang > Fix For: 0.8.0 > > Attachments: PIG_1426.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
