Abstract: According to one aspect, methods and systems are provided for modifying an encryption scheme in a database system. The methods and systems can include at least one internal database key; at least one database configured to be encrypted and decrypted using the at least one internal database key; a memory configured to store a master key; a key management server interface configured to communicate with a key management server; and a database application configured to receive, into the memory, the master key from the key management server via the key management server interface, and encrypt and decrypt the at least one internal database key using the master key.

Abstract: Methods and systems are provided for selectively employing storage engines in a distributed database environment. The methods and systems can include a processor configured to execute a plurality of system components, that comprise an operation prediction component for determining an expected set of operations to be performed on a portion of the database; a data format selection component for selecting, based on at least one characteristic of the expected set of operations, and at least one storage engine for writing the portion of the database in a selected data format. According to one embodiment, the system includes an encryption API configured to initialize callback functions for encrypting and decrypting database data, a storage API for executing the call back functions, a database API configured to manage database operations (e.g., read and write requests), wherein the database API calls the storage API to access data on a stable storage medium.
