Patent number: 11892999Abstract: A system and method for faster access for compressed time series data. A set of blocks are generated based on a table stored in a database of the data platform. The table stores data associated with multiple sources of data provided as consecutive values, each block containing index vectors having a range of the consecutive values. A block index is generated for each block having a field start vector representing a starting position of the block relative to the range of consecutive values, and a starting value vector representing a value of the block at the starting position. The field start vector of the block index is accessed to obtain the starting position of a field corresponding to a first block and to the range of the consecutive values of the first block. The starting value vector is then determined from the block index to determine an end and a length of the field of the first block.Type: GrantFiled: January 19, 2022Date of Patent: February 6, 2024Assignee: SAP SEInventors: Gordon Gaumnitz, Robert Schulze, Lars Dannecker, Ivan Bowman, Daniel James Farrar

Patent number: 11656960Abstract: Disclosed herein are system, method, and computer program product embodiments for disaster resilience of applications managed by Kubernetes operators. An embodiment operates by creating an orchestration and worker cluster, where the worker cluster is coupled to the orchestration cluster by a proxy server. Custom resources are deployed to the orchestration cluster and custom resource controllers are deployed to the worker cluster. The proxy server federates these custom resources between the orchestration cluster and the worker cluster. During disasters, the worker cluster is recreated and reconciled to prevent loss of the federated cluster.Type: GrantFiled: March 18, 2021Date of Patent: May 23, 2023Assignee: SAP SEInventors: Nathan Auch, Ivan Bowman, Daniel Kirmse, Henning Zahn

Patent number: 11238023Abstract: A system and method include storing a table of time series data in a database of a data platform, the table of time series data representing a set of time series blocks. Each time series block of the set of time series blocks has a time series of equally-incremented time intervals and a run length. Each time interval of the time series is associated with one or more values. The run length has a starting position with at least one starting value and an ending position with at least one ending value. The starting position and the at least one starting value is stored for each time series block in a column store of the database. Then, a compressed index is generated in the column store of the database for each time series block, the compressed index comprising the starting position and the at least one starting value.Type: GrantFiled: December 16, 2019Date of Patent: February 1, 2022Assignee: SAP SEInventors: Gordon Gaumnitz, Robert Schulze, Lars Dannecker, Ivan Bowman, Dan Farrar

Patent number: 10496656Abstract: Disclosed is a system and method for improving database memory consumption and performance using compression of time stamp columns. A number of time stamps of a time series is received. The time stamps have a start time, and are separated by an equal increment of time that defines an interval. The start time and interval are stored in a dictionary of a column store of a database. An index is generated in the column store of the database, the index having a number of index vectors. Using the index vectors, each time stamp of the number of time stamps can be calculated from the start time stored in the dictionary and the position in the time series based on the interval stored in the dictionary.Type: GrantFiled: July 8, 2014Date of Patent: December 3, 2019Assignee: SAP SEInventors: Gordon Gaumnitz, Robert Schulze, Lars Dannecker, Ivan Bowman, Dan Farrar
