class User:
  last_purchase = ff.Stream(offline_store=snowflake, online_store=redis, type=ff.Float32)

client.write_feature(User.last_purchase, (user_id, new_value))

This example showcases how to leverage streaming functionality within Featureform. In this scenario, the feature last_purchase of the User entity is designated as a stream. The offline_store (here, snowflake) and online_store (here, redis) specify storage destinations. The data type, in this case, is set to ff.Float32. By utilizing client.write_feature, you can update the last_purchase feature in real time, enhancing the accuracy and timeliness of your data-driven processes.
