This disclosure provides methods and techniques of referencing row access policy (RAP) protected mapping tables in a RAP for a data table are disclosed herein. An example method of referencing a mapping table in a data table using nested RAP includes defining, by a processing device, a first access policy for the mapping table to control access by specific users or under specific conditions. The processing device further defines a second access policy attached to the data table referencing the mapping table. The processing device in response to a query, executes the second access policy of the data table to provide a response or operation of data associated with the data table and the mapping table. Executing the second access policy invokes executing the first access policy of the mapping table.

Nested row access policies

Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.

Row-level security

Systems and methods for managing column hiding are provided. The systems and methods receive, from a client device, a query associated with a table. The systems and methods determine an access restriction associated with the client device. The systems and methods identify a column of the table that is restricted by the access restriction associated with the client device. In response to identifying the column of the table that is restricted by the access restriction associated with the client device, the systems and methods provide a result of the query that excludes data corresponding to the column.

Column hiding management system

Several systems, apparatuses, and methods are described. A data transmission that includes data indicating a first search query for an item of a publication system is received from a client machine. A first plurality of search results is determined from listed items based, at least in part, on the first search query, and the first plurality of search results are each associated with a price. A range of prices associated with a first subset of the search results is determined based on a price distribution range including a median price associated with the first search results, or a utility cost function using a plurality of price quantiles and a plurality of price values included in different price quantiles. The determined first search results and the range of prices associated with the first subset of the first search results are transmitted to the client machine for display.

Dynamically adjusted results for search interface

Aspects of the present disclosure address systems, methods, and devices for tracking object dependencies in a cloud database system. An object dependency created between a referencing object and a referenced object is detected. Based on detecting the object dependency, a dependency record is generated. The dependency record includes dependency information describing the object dependency between the reference object and the referenced object. The dependency record is stored in a database of dependency records.

Tracking object dependency information in a cloud system

A user may submit a search query to a search engine, which may process the search query and generate a set of results. Previous actions of the user or of other users may be used to identify recommended search queries. The recommended search queries may be presented to the user along with the search results for the query. The location of the recommended search queries may be fixed, set by the user, or determined on a query-by-query basis. A user interface element operable to cause the presentation of one or more recommended search queries may be presented after a delay. After an additional or independent delay, the recommended search queries may be presented automatically. The delays may be fixed, set by the user, or determined on a query-by-query basis.

Search guidance

A broadband light source includes a rotatable drum coated with plasma-forming target material, a rotational actuator configured to rotate the rotatable drum, and a rotary encoder connected to the rotatable drum. The broadband light source may include a linear actuator configured to axially translate the rotatable drum and linear encoder connected to the rotatable drum. The broadband light source includes a pulsed laser source configured to direct pulsed illumination to a set of spots on the material-coated portion of the rotatable drum for exciting the plasma-forming target material and emitting broadband light as the drum is actuated. The broadband light source includes a control system. The control system is configured to receive one or more rotational position indicators from the rotary indicator and control triggering of the laser source based on the one or more rotational position indicators from rotary encoder.

Object dependency tracking in a cloud database system

Method, system, and programs for providing content recommendation are disclosed. A first set of candidate content items may be generated based on a user profile, and a second set of candidate items may be generated based on the likelihood that the user will click a corresponding candidate content item in the second set. The candidate content items in the first and second sets may be ranked together using a learning model and presented to the user as content recommendations based on their rankings. The likelihood that the user will click a given candidate content item in the second set may be estimated based on similarities between the given content item and content items related to the given content item. Such a similarity may be computed based on activities performed by users who have viewed both the given content item and a related content item.
