Abstract: Traversal hooks are based on an event-oriented programming model and provide an expressive mechanism to extend a graph traversal operator with domain-specific coding. A traversal operator can visit (i.e., traversal events) vertices and edges of a graph in an ordered manner. Related apparatus, systems, techniques and articles are also described.

Abstract: A system, computer-implemented method, and a computer-readable storage medium for a data graph traversal are provided. The input parameters for traversing the data graph are received. The data graph having a set of vertices and a set of edges are stored in a column based format in a memory cache of a computer device based on the input parameters is traversed. The traversal generates a set of traversed vertices that are the result of the graph traversal.

Abstract: Disclosed herein are system, method, and computer program product embodiments for performing ad-hoc analytical queries of graph data. An embodiment operates by receiving a graph pattern for a subgraph of interest. The facts of interest are then selected from graph data based on the received graph pattern. Dimensions are then defined based on a dimension seed pattern and a set of level expressions, and measures are defined based on a computation function and an aggregation function. A graph cube is formed based on the selected facts and the defined dimensions and measures. Because the facts, dimensions, and measures of interest are defined at the time of an analytical query, a user does not have to define such facts, dimensions, and measures, or know which analytical queries will be of interest, at the time of data collection.

Abstract: This disclosure describes documenting modifications to configuration file that can affect (e.g., change) behavior of a component of a service provided by a database management system. The service can collect metadata associated with a request to modify a configuration file affecting the behavior of the component of the service. The service can modify the configuration file in response to the request. The modification can change the behavior of the component of the service. The service can generate data representing documentation of the modification to the configuration file and the metadata. The data can represent the documentation being configured for storage by the database management system. Related apparatuses, systems, methods, techniques and articles are also described.

Abstract: Disclosed herein are system, method, and computer program product embodiments for interactive exploration of graph data. An embodiment operates by compiling a data query in any database-readable language based upon an input parameter. A data query of a graph data set is then conducted but is halted when a breakpoint generated from the input parameter is reached. Halting the data query includes partitioning a data subset from the graph data set. The data subsets is then displayed.
