Abstract: Disclosed aspects relate to agent flow arrangement management in a distributed commit processing environment. A first set of agent utilization data may be collected with respect to a first commit processing agent. A second set of agent utilization data may be collected with respect to a second commit processing agent. An agent flow arrangement may be determined based on a first value with respect to the first set of agent utilization data exceeding a second value with respect to the second set of agent utilization data. The agent flow arrangement may have the first commit processing agent subsequent to the second commit processing agent. The distributed commit operation may be processed using the agent flow arrangement which has the first commit processing agent subsequent to the second commit processing agent.

Abstract: A method, a computer program product, and a computer system for scheduling downloads based on metadata in a client-server topology. A server receives from a client application a request for scheduling a download of a file, wherein the request for scheduling the download of the file comprises a requirement of a time period for downloading the file. The server fetches information from one or more metadata sources. The server determines an optimal time for downloading the file, based on the requirement of the time period and information from one or more metadata sources. The server sends a response with the optimal time and information for downloading the file. The server receives from the client a request for downloading the file at the optimal time. The server serves, at the optimal time, the file to the client application.

Abstract: A method for a distributed computing system managing vertically partitioned data includes receiving a query for a first row of data, where a first column of the first row of data is stored in a first data server and a second column of the first row of data is stored a second data server. The method translates the query for the first row of data into two queries, wherein a first translated query is for the first column of the first row of data and a second translated query is for the second column of the first row of data. The method sends the first translated query to the first data server and the second translated query to the second data server. Responsive to receiving the first column and the second column of the first row of data, the method sends the first column and the second column of the first row of data.
