Some database systems may implement encryption services to improve the security of data stored in databases or on disks. The systems may implement encryption using multiple encryption keys. For example, a worker server may implement a system call interceptor, such as a filesystem in userspace (Fuse) driver. The system call interceptor may intercept system calls (e.g., associated with query or extract, transform, and load (ETL) jobs) as they enter or exit the kernel. The system call interceptor may determine whether data sets associated with the jobs are marked for encryption, and may perform an encryption process on the data sets. A worker may encrypt and store data sets on a worker disk or at a file store, or may retrieve and decrypt the data sets. The system may additionally manage encryption keys, and may provide mechanisms for archiving or revoking encryption keys while maintaining user access to stored data sets.

Methods are disclosed for dynamic node allocation for a server system that can automatically heal on failure&#x2014;minimizing the need for static configuration&#x2014;dynamically adjusting server resources to match load, and minimize end user wait times. The disclosed methods dynamically allocate nodes to increase capacity for a platform that accepts data queries. Additionally disclosed is a system for rolling version update deployment: workers maintain org lists of org-task-queues that they service; org-affinities between the workers and the org-task-queues require the workers to have access to local copies of immutable data sets to service org-tasks from the org-task-queues of the orgs that they service. A leader running on a worker implements a healing and balancing service that maintains worker redundancy, manages the workers' org-affinities to accumulate orgs on their respective org-lists. The leader implements messaging to the workers to update to a new software version and monitors completion of updates.

An in-browser proxy enables an application in a frame to make a cross domain request. The proxy executes within the browser, which has a first domain. The browser provides a frame in which a client application executes, which has a second domain. The request from the client application is a request for data access to the external domain. The proxy identifies a registration of the client application, and forwards the request to the external domain. The proxy receives a response to the request and provides the response back to the client application within the frame.
