Abstract: The subject technology receives a query. The subject technology performs a lookup operation on a shadow cache. The subject technology performs a validation process on the particular query plan for determining a cache hit on the shadow cache. The subject technology performs a program building process to update the particular query plan with additional information for executing the particular query plan. The subject technology performs a compilation process to compile an updated program of the updated particular query plan. The subject technology determines that the updated particular query plan is cacheable based at least in part on the compilation process. The subject technology registers the updated particular query plan as a new entry in the shadow cache. The subject technology sends the updated program to an execution node for executing the updated particular query plan.

Abstract: The subject technology receives a query, the query including a statement for performing the query. The subject technology performs a first lookup operation on a multi-phase cache based on the query. The subject technology performs, in response to a first cache miss of the multi-phase cache, parsing of the statement from the query. The subject technology performs, based on the parsing, a compilation process on the query to generate a compiled query plan, the compilation process determining an optimization and a generalization for the query. The subject technology determines that the compiled query plan is cacheable. The subject technology registers, in response to the compiled query plan being cacheable, a dummy entry in the multi-phase cache.

Abstract: Embodiments relate to providing at least one response to a user of a user device using a visual assistant, wherein the response is based on at least one user query. In an embodiment, the virtual assistant system receives the user query through a virtual multimedia contact, wherein the virtual multimedia contact is invoked by receiving a user command from the user through an interface. Thereafter, the virtual assistant system determines the response based on the user query. Further, the virtual assistant system selects a visual assistant (e.g., virtual character) for representing the response and subsequently provides the response to the user device using the visual assistant by transmitting the response to the user device using the visual assistant.

Abstract: The present disclosure relates generally to managing security artifacts for a software application executing on a software stack. Techniques are described for defining a security configuration such that each layer of the software stack may be associated with one or more datastores, each datastore including one or more security artifacts for a particular layer. The security configuration may specify, for example, an order in which the various datastores are to be accessed when a request is received for a security artifact that is available from multiple datastores. Using the security configuration, access to security artifacts can be handled in connection with requests generated through a particular layer in the stack. A system managing the security artifacts can provide a unified view of the datastores such that, from the end-user's perspective, there is only one logical datastore.

Abstract: In accordance with an embodiment, described herein is a system and method for providing security services using a security configuration template in a multi-tenant environment. The system can load a security configuration template in memory when the multi-tenant environment starts, and can use the security configuration template to create a multi-headed tree to represent tenant-specific security configurations. Each head of the multi-headed tree can represent a root node of either the security configuration template or a tenant-specific security configuration. Each tenant-specific security configuration can reuse one or more nodes in the security configuration template by referencing those nodes, and can include one or more new nodes created from the security configuration template by replacing each placeholder therein with tenant-specific values.

Abstract: Application customization enables many different types of customers, from small companies to large multinational enterprises, to use various applications provided by a cloud service provider. To accommodate these customizations, previous systems generally require manual human intervention to identify custom, customized, and cloud service provider authorization policies (also referred to herein as “seed” authorization policies) and to decide how each type of authorization policy should be upgraded. When applications are customized, artifacts that represent those customizations can be created. In some embodiments, the customizations can include new resources or entitlements, and grants to new roles. In addition to new resources, entitlements, and grants, existing resources, entitlements, and grants can be modified and artifacts corresponding to those modifications can be generated.
