Abstract: Disclosed are various embodiments of systems, methods, and computer programs that can facilitate processing of large data sets from data sources. Examples of the disclosure can allow a client to perform data processing tasks in computing resources that are external to a data source from which the data is retrieved rather than relying upon the computing resources of the data source.

Abstract: Systems and methods are described for allocating computing resources to load data into a database. In some aspects, a database service obtains a request to load a number of data chunks. Responsive to the request, the database service scales a number of worker threads to load the data chunks. The scaling may include selecting a maximum number of worker threads to load (e.g., concurrently) the data chunks based on a number of data chunks, and assigning individual worker threads to load individual data chunks. The scaling may additionally include tracking a number of available worker threads relative to the maximum number of worker threads to reassign a first worker thread to load another data chunk upon the completing loading a prior data chunk, or assign a new worker thread that has become available based on a change in the maximum number of worker threads.

Abstract: Methods, systems, and computer-readable media for global column indexing in a graph database are disclosed. A plurality of data elements of a graph database are stored. The triples comprise identifiers, column names, and values. The column names are globally scoped in the graph database and are associated with data types. Indices corresponding to the column names are created. A particular one of the indices comprises one or more of the values associated with the corresponding column name. A query is performed on the graph database using one or more of the indices corresponding to one of more of the column names associated with the query.

Abstract: Methods, systems, and computer-readable media for query language interoperability in a graph database are disclosed. Data elements are inserted into a graph database using one or more of a plurality of graph database query languages. The graph database query languages comprise a first graph database query language associated with a first data model and a second graph database query language associated with a second data model. The data elements are stored in the graph database using an internal data model that differs from the first and second data models. One or more of the data elements are retrieved from the graph database based at least in part on a query. The query is expressed using a different graph database query language than the graph database query language used to insert the one or more retrieved data elements.
