This is an epic.
In order to make MainStash work correctly in an active-active DC environment, we need to know what each component that uses MainStash expects from the service.
This consists of the following:
- Knowing what storage characteristics are important for making a decision
- Knowing which components use MainStash for WMF servers
- Knowing the characteristics of each component
The outcome of this will be a matrix of components x characteristics, which will be an input for deciding about strategy on MainStash implementations.
