Hybrid storage and load system with ROWID lookup
SAP SE, Walldorf, Germany, has been assigned a patent (11514028) developed by Pathak, Amit, Pune, India, Florendo, Colin, Marlborough, MA, Khadilkar, Pushkar, Pune, India, and Schulze, Robert, Walldorf, Germany, for “hybrid data storage and load system with rowid lookup.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “System, method, and various embodiments for providing a hybrid data storage and load system are described herein. An embodiment operates by receiving a lookup request comprising a row identifier (ROWID) corresponding to a row of a table of a database. Which of a first set of pages corresponds to a sorted position of the ROWID is identified. The identified page of the first set of pages is loaded from the disk storage to the memory storage. A sorted row position of the ROWID is identified from a memory block of the loaded page from the first set of pages. One of a second set of pages that includes the sorted row position is identified. The identified one of the second set of pages is loaded from the disk storage into memory. The loaded identified one of the second set of pages is searched for the unsorted position of the ROWID.

Decentralized storage of personal data
SAP SE, Walldorf, Germany, has been assigned a patent (11481513) developed by Rolle, Benny, Karlsruhe, Germany, for adecentralized storage of personal data.”

Personal data associated with a data subject may be received or derived in association with a virtual identity of the data subject. The personal data may be stored, and identifying information that is linked to the personal data may be stored, where the identifying information is included in shadow data associated with the personal data. The identifying information may include a virtual identity identifier of the virtual identity, and, in some examples, a creation timestamp of the personal data. When a request to retrieve personal data for a data subject, shadow data storage may be searched to locate identifying information provided in the request, and personal data items linked to the located identifying information may be returned as a result of the request.

Cloud architecture for replicated data services
SAP SE, Walldorf, Germany, has been assigned a patent (11461201) developed by Pound, Jeffrey, and Saxena, Hemant, Waterloo, CA, for acloud architecture for replicated data services.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods include a set of delta copies received from cluster node replicas of a replica set and stored on a main data storage on the cloud. A cloud storage service internally replicates the data from the delta copies and provides fault-tolerance and high availability against storage failures. All cluster node replicas participate in a delta copies merge. Each replica writes their deltas to an independent location in a shared storage on the cloud. Then, the delta merge includes deltas from all replicas when building a new main storage. This ensures that the data from all replicas are included in the delta merge.

SAP SE, Walldorf, Germany, has been assigned a patent (11423000) developed by Gohad, Nilesh, Pune, India, Dragusanu, Adrian, North Vancouver, Canada, Kulkarni, Neeraj, Berlin, Germany, and Gala, Dheren, Bangalore, India, for “data transfer and management system for in-memory database.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Various embodiments for providing a data transfer and management system are described herein. An embodiment operates by determining that data of a column is stored in a column loadable format in which all of the data of the column is moved from the disk storage location to a memory responsive to a data request. A data vector that identifies a plurality of value IDs corresponding to at least a subset of the plurality of rows of the column, is identified. A page format that provides that a portion of the data of the column across a subset of the plurality of rows is moved from the second disk storage location into the memory responsive to the data request is determined. The entries of the data vector are requested, converted from column loadable format into the page persistent format, and stored across one or more memory pages.

The patent application was filed on 2020-05-20 (16/878894).

Distributed storage orphan scan
SAP SE, Walldorf, Germany, has been assigned a patent (11422743) developed by Kandiyanallur, Vivek, San Francisco, CA, Feng, Jia, Pleasanton, CA, Chernavin, Alexander, San Carlos, CA, Chung, Chitong, Mountain View, CA, Avula, Shyam Sunder Reddy, San Ramon, CA, Guo, Xin, Fremont, CA, Hamilton, Scott, Aldie, VA, Jacobs, Clay, Hillsborough, CA, de Castro, Christopher, Farmington, MN, and Ghosh, Kaushik, Santa Clara, CA, for a distributed storage orphan scan.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage system includes a primary storage system and a secondary storage system. The secondary storage system stores the actual data and the primary storage system stores metadata for the actual data. The metadata references at the primary storage system may be deleted without deleting the corresponding data at the secondary storage system. Snapshots of the metadata at the primary storage system are sent to the secondary storage system. The secondary storage system can compare two metadata snapshots received from the primary storage in order to determine whether data stored at the secondary storage system has been deleted at the primary storage system for longer than a retention period. Such data may be deleted to free up storage space at the secondary storage server.

The patent application was filed on 2020-06-08 (16/896033).

Use of files for efficient analysis and storage of time-series
SAP SE, Walldorf, Germany, has been assigned a patent (11423040) developed by Schuerings, Christian, Düsseldorf, Germany, Schoenfeld, Ralf, Tettnang, Germany, and Weigold, Florian, Bensheim, Germany, for use of files for efficient analysis and storage of time-series.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An approach to time-series data handling involves use of a logical data file structure within a multi-layer file storage. Client systems may ingest time-series data to this logical data file structure by writing or appending the time-series data to at least one file in the logical data file structure and adding metadata describing contents of the at least one file to a metadata catalog. Related apparatus, systems, techniques and articles are also described.
