Question

我将适配器与room-db Flowables绑定

db.myDao().loadByTrackId(tracksId)
                .observeOn(AndroidSchedulers.mainThread())
                .subscribeOn(Schedulers.io())
                .subscribe({ comments ->
                    Timber.d("setDataAD " + comments.size())
                    adapter.setData(comments.toMutableList())
                }, ...
                )

我从某个地方更新了会议室数据库

db.myDao().updateComments(pair.first.data, pair.second.data)

dao：

@Transaction
fun updateComments(commentOrigin: List<Comment>, commentNew: List<Comment>) {
    delete(commentOrigin)
    insertAll(commentNew)
}

@Delete
fun delete(comments: List<Comment>)

@Insert(onConflict = OnConflictStrategy.REPLACE)
fun insertAll(comments: List<Comment>)

现在删除3个并插入3个并使用@Transaction的方法时，我假设一个事件与Flowable有关，但我测量了Flowables的烟火

如何解决这个问题，使其仅获得一个事件/ Flowable？或换句话说：如何防止Flowables反映一些数据库更新
