Modify Column.keys in projection query
|

Hi Alexander, Readers of this list can help you better if you provide the query you tried on one of the example graphs or a sample graph you provide yourself. The Column.keys and Column.values are not useful for the project() step. If the properties of your vertices are called time and capacity you can do something like (not tested): project('time','capacity).by(values('time).map{it.get().substring(1,4)}).by(values('capacity).map{it.get().substring(1,4)}) The time and capacity args in the project step are used as keys in the resulting Map.

Hello Everyone, I am having a simple projection query which ends with project('time','capacity).by(keys).by(values) Query itself works fine, but I need to make a substring of each key. Is there a way to do this? |
