We can't really recommend a way to start root sagas however we can certainly explain better the effect. I think it's probably worth creating a dedicated documentation page.
your examples 1.
// single entry point to start all Sagas at once
export default function* rootSaga() {
yield [
saga1(),
saga2(),
First: You cannot use $.Promise(); because it does not exist. A deferred object is an object than can create a promise and change its state to resolved or rejected. Deferreds are typically used if you write your own function and want to provide a promise to the calling code. You are the producer of the value.
A promise is, as the name says, a promise about a future value. You can attach callbacks to it to get that value. The promise was "given" to you and you are the receiver of the future value. You cannot modify the state of the promise. Only the code that created the promise can change its state.
By default there are 16 databases (indexed from 0 to 15) and you can navigate between them using select command. Number of databases can be changed in redis config file with databases setting. để chọn database
select index
By default, it selects the database 0. To select a specified one, use redis-cli -n 2 (selects db 2)
CREATE KEYSPACE IF NOT EXISTS k1 WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '1'} AND durable_writes = true;
