  • DATABASE WORKLOAD CAPTURE AND REPLAY
    Publication number: 20170322972
    Abstract: Technologies are described for facilitating data workload capture, workload replay, and comparing the performance of a plurality of database systems. A plurality of requests for database operations are received from one or more database clients. The requests for database operations are executed. For the plurality of requests for database operations, execution context information is generated for a plurality of execution contexts. For the plurality of requests for database operations, a plurality of performance measures are generated. The execution context information and the performance measures are stored in a workload capture store, such as a file. The workload capture file is useable to replay the captured workload at a second database system using at least a portion of the execution context information and at least a portion of the performance measures.

  • Client-side partition-aware batching of records for insert operations
    Patent number: 9720949
    Abstract: Client-side partition-aware batch insert operations are presented. For example, a server generates partition metadata, which is provided to a client. The client uses the partition metadata to determine the database nodes to which to send batch insert requests. For example, the client divides batch insert data, such as records for a partitioned table, among multiple database nodes having partitions of the table. The client issues batch insert requests to the respective database nodes for execution. When executed by the database nodes, batch insert operations can be performed in parallel.
