Jan van der Lugt updated GIRAPH-192: ------------------------------------ Attachment: GIRAPH-192.patch > Move aggregators to a seperate sub-package > ------------------------------------------ > > Key: GIRAPH-192 > URL: https://issues.apache.org/jira/browse/GIRAPH-192 > Project: Giraph > Issue Type: Improvement > Components: examples > Affects Versions: 0.2.0 > Reporter: Jan van der Lugt > Assignee: Jan van der Lugt > Priority: Minor > Fix For: 0.2.0 > > Attachments: GIRAPH-192.patch, GIRAPH-192.patch > > Original Estimate: 2h > Remaining Estimate: 2h > > Since aggregators will be re-used throughout many projects and algorithms, it > makes sense to implement the most common ones in a separate sub-package. This > will reduce the time required for users when they implement their projects > based on Giraph, because the required aggregators are already in place. I > implemented the following ones: > for int/long/float/double: min, max, product, sum, overwrite > for boolean: and, or, overwrite > Most of them speak for themselves, except for the overwrite one. This > aggregator simply overwrites the stored value when a new value is aggregated. > This is useful when one node is in some way a master node (for example a > source node in an routing algorithm), and this node wants to broadcast a > value to all other nodes. > Attached is a patch against trunk implementing the aggregators and patching > some existing files so they use the .aggregators package instead of the > .examples one. -- This message is automatically generated by JIRA.
