## Using two at a time
If you want to use two different adapters at the same time that's easy. Just add both to the corresponding slices:
If you want to use two different adapters at the same time that's easy. Just use the `policies.Seq*` functions:
```go
relay.StoreEvent = append(relay.StoreEvent, db1.SaveEvent, db2.SaveEvent)
relay.QueryEvents = append(relay.QueryEvents, db1.QueryEvents, db2.QueryEvents)
relay.StoreEvent = policies.SeqStore(db1.SaveEvent, db2.SaveEvent)
relay.QueryStored = policies.SeqQuery(db1.QueryEvents, db2.QueryEvents)
```
But that will duplicate events on both and then return duplicated events on each query.
