    Abstract: In some database systems, a user device may query for data records using a procedural language extension to structured query language (PL/SQL) call. However, some databases may not be configured to process PL/SQL code. In these cases, a virtual machine may intercept the PL/SQL call, and may transform the call to a format usable by the database. For example, the virtual machine may deconstruct the PL/SQL call to determine the procedural and query functions that comprise the PL/SQL call. The virtual machine may then search a database for non-PL/SQL code snippets that correspond to these determined functions, and may generate non-PL/SQL code (e.g., Java code) that may perform the same functions as the PL/SQL call. The virtual machine, the database, or a combination of the two may execute the non-PL/SQL code to retrieve the data records from the database, and may return the records to the user device.

    Abstract: Disclosed techniques relate to storing a key cache within a secure enclave. In some embodiments, a computing system receives, from an application, a request to access a database, where the request is associated with a particular account. The computing system then accesses, using an identifier associated with the particular account, a key cache stored in a secure enclave of a memory of the computing system to determine at least one private key associated with the request, where the key cache stores private keys of a key management system (KMS) for a plurality of accounts. The computing system performs a cryptographic operation for accessing the database within the secure enclave using the at least one private key. In various embodiments, disclosed techniques may improve the security of cryptographic private keys cached for a plurality of tenants.
