Abstract: A computer system receives a query for data stored in a relational database management system. The system generates a query plan based on the query, and generates an execution plan based on the query plan. Generating the execution plan includes generating first instructions to a physical resource to execute a portion of the query plan. The computer system determines a first resource cost associated with executing the portion of the query plan using a first CPU and a second resource cost associated with executing the portion of the query plan using a first FPGA of the physical resource. Upon determining that the second resource cost is lower than the first resource cost, the system generates second instructions to the FPGA to execute the portion of the query plan, and executes the execution plan to retrieve the data.

Abstract: A sync server responds to messages from a client to synchronize data between a client dataset and a reference dataset. Various messages may be received from the client, including changes to the client dataset, requests for confirmation of received changes, or requests for changes to the reference dataset. When the server receives client changes, the server reads record ID's from the messages, writes the ID's into a change ID list, and places the changes into a queue for processing. When the server receives a request for confirmation of changes, the server uses the change ID list to confirm receipt of changes, including changes that have not yet been processed. If the server receives a message that requires that the reference dataset be up-to-date, such as a request for changes from the reference dataset, the sync server processes all of the changes in the queue before processing the new message.
