Abstract
A subscription storage service of a provider network may be used to select a particular datastore to store a topic subscription record for an IoT device (e.g., after the IoT device subscribes to an MQTT topic). The service may select the particular datastore based on the type of the subscription (e.g., non-wildcard vs. wildcard subscription) and one or more criteria associated with the topic (e.g., subscribe operation TPS for the topic). This may allow the service to store wildcard subscriptions to a different structure and/or datastore (e.g., a 'trie' structure of an in-memory data store), while offloading the storage of non-wildcard subscriptions to another type of datastore (e.g., a key-value store) that has lower performance and/or operational cost to store data.
