I DOUBT this but its worth a shot
I take the RelationPredicateBucketText
[MAINDB].[dbo].[obj].[MainId] > @MainID2
Replace the ParameterNames with the Values
[MAINDB].[dbo].[obj].[MainId] > 100
Use this as the Cache Key (Along with the Entity Name)
I get the Key Back, is there a way to match this string with an Entity?
Obj:SomeEntity
MainID: 10
????
