# Type

The type of virtual database. This value is either `Distributor` or `Combinator`.

- Distributor. The virtual database forwards client actions to one of the IDOL server databases that it maps to (these databases must be identical copies of each other and contain the same data). The way it forwards the query is determined by the DistributionMethod.

- Combinator. The virtual database forwards client actions to all the IDOL server databases that it maps to. It collates and sorts the results before it returns them to the clients.

NOTE: You cannot configure virtual databases when you set SimpleCombinatorMode to `True`.
