    Abstract: A computer system provides shared access to electronic data assets. The system may perform operations including: receiving, from a first user, a request to access a shared data asset, wherein: the shared data asset is associated with a shared data asset object, and the shared data asset object identifies at least a second user authorized to approve sharing of the shared data asset; in response to receiving the request from the first user: generating a data access request object including at least an identification of the first user and an identification of the shared data asset object; and providing an indication of the data access request object to the second user associated with the shared data asset object; receiving, from the second user, an approval of the request; and in response to receiving the approval of the request from the second user: granting the first user access to the shared data asset associated with the shared data asset object.

    Abstract: A computer-implemented method for efficiently performing a database join in a distributed data processing system comprising multiple computational nodes, the method comprising determining a first set of one or more columns of a first database table and a second set of one or more columns of a second database table on which the join is to be performed; estimating a size of the rows of the first table which have a particular combination of values in the first set of columns; computing a salt factor n based on the estimated size of rows and further based on a processing capacity of a computational node of the distributed data processing system; assigning one of n different salt values to each row of the first table having the particular combination of values in the first set of columns; for each row of the second table having the particular combination of values in the second set of columns into n rows, expanding the row into n row, and assigning to each expanded row a different one of the n salt values; and performing a join operation on the modified first and second tables, wherein the rows of the first and second tables have the same combination of values in the first and second sets of columns and the same salt value are joined on the same computational node.

    CPC classification number: G06F9/4881

    Abstract: A system and methods for queuing processing jobs. The system is configured to receive a processing job associated with a user; score the processing job; apply one or more bounds; add the processing job to a queue; order the queue based on scores of processing jobs in the queue; and sample processing jobs from the queue for dispatch for processing. Sampling the jobs from the queues can comprise updating scores, updating application of bounds, and updating ordering of the queue; reading a batch of processing jobs from a top of the queue; attempting to dispatch the processing jobs of the batch for processing; removing from the queue any dispatched processing jobs; increasing the batch size by a constant factor; determining whether a maximum batch size is reached, or all processing jobs in the queue were in the batch.
