Abstract
Disclosed techniques relate to caching tenant encryption keys for a multi-tenant database. In some embodiments, a computing system encrypts data for a database in a multi-tenant database system using encryption keys assigned to respective tenants that are using the database. The computing system may store the encryption keys in a cache and, in response to a key rotation request for a first tenant, invalidate an entry in the cache for the first encryption key of the first tenant. The computing system may block writes for the first tenant until a new key is cached (e.g., based on retrieval from a key management system). In various embodiments, disclosed techniques may reduce encryption latency.
