There are two categories of reactive sequences—hot and cold. These functions affect the usage of the implementation directly. Hence, we need to understand them:
- Cold: The cold publishers start to generate data only if it receives a new subscription. If there are no subscriptions, the data never comes to the flow.
- Hot: The hot publishers do not need any subscribers to generate the data flow. When the new subscriber is registered, the subscriber will only get the new data elements emitted.
