created issue #1

Jul 5, 2017 12:04PM

Component used: Room with RxRoom
Version used: 1.0.0alpha3
Devices/Android versions reproduced on: all

After using Room and RxRoom I was lacking of some functionalities like the ability to return an Single/Completable from insert queries.

For example something like this would be super helpful :
@Insert(onConflict = OnConflictStrategy.REPLACE)
Completable insertAll(CatalogEntry... entries);

@Insert(onConflict = OnConflictStrategy.REPLACE)
Single<Long> insertAll(CatalogEntry... entries);

@Insert(onConflict = OnConflictStrategy.REPLACE)
Single<List<Long>> insertAll(CatalogEntry... entries);

Also when doing a query for retrieving a list, why should I use Flowable, if I just want to get a list my query should be like:

@Query("SELECT * FROM catalog_entries")
Single<List<CatalogEntry>> getAll();

Thanks for your work ! I love it already :)

Also, it would be great to return Observable, cause Flowable has some overhead.

Assigned to yb...@google.com.

We are going to add Single for queries (and Maybe) but for @insert, @Update and @Delete it is a bit more tricky because we would be reading those values when the computable runs, in which case developer may change them by mistake. We've not decided whether we want to take that risk or not. (We could copy but that would be additional hidden load, especially if the input is a long list).

#2, flowable can easily turn into an observable, would you like to escalate on why you think the overhead is a problem?

ji...@gmail.com <ji...@gmail.com> #4Jul 17, 2017 07:19PM

Cool for Single/Maybe for queries :)

For @insert, @Update and @Delete I personally would like to have the possibility to have Single/Maybe... because I will 100% of the time wrap the call into a Single to make it asynchronous and have the possibility to chain other actions with it. I understand that copying entries will take additional resources but in that case we'll have the possibility to not use the RX return type.

That my opinion ^^
Thanks !

Shouldn't this be typed as a feature request?

This issue is half year old and it's still not implemented. Without this the library is unusable.

ju...@gmail.com <ju...@gmail.com> #17Jun 28, 2018 12:20PM

This would be a nice improvement!

My initial response is to wrap the insert in a Completable when exposing the call to a consumer because of the time spent writing to the file system on the main thread. Guessing would probably desire the same API for delete.

Out of the box without LiveData/RxJava support for those types of calls it would violate strict rules and run into the guards of Room ensures that database is never accessed on the main thread.

It's really necessary thing and it's not implemented still(

we are targeting this for 2.1.

commit ecce72935bbe7987a9c0c1639f4aa245153c717a
Author: Florina Muntenescu <florinam@google.com>
Date: Fri Sep 07 15:36:18 2018

Add RxJava support for Delete and Update methods in Room.

Support for update and delete returning Integer also added.
Now, update and delete support:
* void
* int
* Integer
* Completable
* Single<Integer>
* Maybe<Integer>

Refactored the DeleteOrUpdateMethodAdapter to hold the return type, like InsertMethodAdapter is.

Test: DaoWriterTest, TypeAdapterStoreTest, kotlin integration tests
