use the execute methods instead of asObservable

[Ben Tseytlin]

Won’t that execute on the main thread? I was taking advantage of Rxjava thread handling so it could perform on IO and i could post results back to main thread

[alec]

then what jake said

[jw]

or Single.fromCallable(query::execute)

[Ben Tseytlin]

Will give it a try. But about point (1), how should one remove the listener if they do want it? I see this causing a leak if the listener stays around

[alec]

when the disposable is disposed it will unregister the listener

[jw]

take(1) will unsubscribe after the first emission which will cause the listener to be removed

Super excited about SQLDelight, we’re working it into the project now and so far it’s awesome. Thanks so much for the help and the sweet library

[Ben Tseytlin]

will do!
