----------------------------------------
Assignee: Kasper Sørensen
> ColumnNameAsKeysRowConverter should be able to traverse nested columns
> ----------------------------------------------------------------------
>
> Key: METAMODEL-92
> URL: https://issues.apache.org/jira/browse/METAMODEL-92
> Project: Metamodel
> Issue Type: Improvement
> Affects Versions: 4.2.0-incubating
> Reporter: Kasper Sørensen
> Assignee: Kasper Sørensen
>
> In some modules we have rows/documents that can have nested objects. For
> instance in the JSON module. Often these modules will use the
> ColumnNameAsKeysRowConverter class to extract values from it's row/document
> objects into MetaModel's rows.
> It would be a big improvement if we allow the user to specify column names
> with a syntax that allows them to denormalize their data and extract
> information even from nested objects. For instance if you have this document:
> {
> "name":{ "first":"Joe", "last":"Sixpack" },
> "gender":"MALE",
> "verified":false,
> "userImage":"Rm9vYmFyIQ=="
> }
> Then a column with the name "name.first" should resolve "Joe" from this
> particular document. I believe we have similar functionality in some of the
> NoSQL modules, so consider how we can best reuse it.
