             Summary: Provide a mutation API
                 Key: TINKERPOP3-744
                 URL: https://issues.apache.org/jira/browse/TINKERPOP3-744
             Project: TinkerPop 3
          Issue Type: New Feature
          Components: process
    Affects Versions: 3.0.0.GA
            Reporter: Bryn Cooke
            Assignee: Marko A. Rodriguez


Currently property mutations to elements are restricted to setting a property to a fixed value and adding/removing.

However for efficient gremlin server side mutations we will need more operations. For instance:
* Incrementing the value of a property.
* String manipulation.
* Setting a property to be the soundex of another property.

All these operations are available when updating a table using SQL.

Currently this sort of thing is handled via sideeffect lambda, however this means deploying custom code to gremlin server instances.

It would be great if we had a more fully featured mutations API. This would allow vendors to implement optimisations if their backend supports the mutation natively.
