Caching results of sub-queries to different locations in a data store may be performed. A database query may be received that causes different storage engines to perform sub-queries to different locations in a data store that stores data for a database. The results of the sub-queries may be stored in a cache. When another database query is received, sub-queries generated to perform the other database query that are the same as one or more of the previously performed sub-queries may obtain the results of the sub-queries from the cache instead of performing the sub-queries again.

Techniques for rapid secure authentication and communications through multitenant components in a provider network are described. A main database cluster can request a burst cluster from a burst service, which can provide the main cluster with a shared secret associated with only a selected burst cluster. The main cluster can use the shared secret to encrypt a value that can be passed, via a proxy, to the selected burst cluster in a connection request. The selected burst cluster can validate that the connection request was truly originated by the main cluster by validating the encrypted value using the shared secret.
