• get state: Get a single state from statestore
• bulk get: Get multiple states(Bulk get) from statestore
• transaction: Execute a transaction on supported statestores
• delete state: Delete specified key from statestore

It creates a client using DaprClient and calls all the state API methods available as example. It uses the default configuration from Dapr init in self-hosted mode.

== APP == State store has successfully saved value_2 with key_2 as key

== APP == State store has successfully saved value_3 with key_3 as key

== APP == Got value: b'value_1'

== APP == Got items: [b'value_1_updated', b'value_2']
