---------------------------------------------
Summary: Create distributed side-effects/reducers
Key: TINKERPOP-1613
URL: https://issues.apache.org/jira/browse/TINKERPOP-1613
Project: TinkerPop
Issue Type: Improvement
Components: process
Affects Versions: 3.2.3
Reporter: Marko A. Rodriguez
Right now, {{groupCount()}}, {{group()}}, {{dedup()}}, {{fold()}}, etc. yield
side-effects or reductions that can potentially be large data structures. As
opposed to {{count()}}, {{sum()}}, and the like which reduce on a single
primitive.
We should be able to maintain distributed representations of the larger data
structures using a hashing method. For example, if the {{groupCount()}} yields:
{code}
["a":1,"b":3,"c":5]
{code}
"a":1 can be on worker 1, "b":3 on worker 3, and "c":5 on worker 3.
In {{GraphActors}} we have much more control regarding how data is laid out
across the cluster and thus, should use this flexibility to support distributed
side-effects/reductions.
