SAP Assigned Two Patents

Caching topology of distributed data storage
SAP SE, Walldorf, Germany, has been assigned a patent (10,552,069) developed by Schreter, Ivan, Malsch, Germany, for “caching the topology of a distributed data storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method can include caching, at a first computing node and a second computing node, a replica of an anchor object. The anchor object can link to a topology object storing elements comprising a distributed data storage system. The first computing node can reside in a first availability zone. The second computing node can reside in a second availability zone. The first availability zone and the second availability zone can be part of a data center. The first computing node and the second computing node can each store a data partition associated with a data container belonging to a tenant. A replica of the topology object can be cached at the first availability zone and the second availability zone. A query requiring data associated with the tenant can be executed based on the cached replica of the anchor objects and/or topology objects.”

The patent application was filed on July 6, 2018 (16/029,454).

Cross-referenced irregular field storage in databases
SAP SE, Walldorf, Germany, has been assigned a patent (10,521,314) developed by Bae, Seyeong, Jang, Ji Hoon, Kwon, Yong Sik, and Kim, Hyeong Seog, Seoul, Korea, for a “cross-referenced irregular field storage in databases.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Improved database consistency and consistency checking may be provided by cross-referenced split data storage for irregular fields using auxiliary pointers. A fixed-size memory slot may be allocated to a database table in a database system, where the fixed-size memory slot has an address. A variable-size memory slot may be allocated to the database table, where the variable-size memory slot has a different address. For an irregular field in the database table, one or more properties of the irregular field may be stored in the fixed-size memory slot. The one or more properties may include a first pointer which may have the address of the variable-size memory slot. For the irregular field in the database table, at least a portion of data of the irregular field and a second pointer, which may have the address of the fixed-size memory slot, may be stored in the variable-size memory slot.”

The patent application was filed on March 30, 2018 (15/942,151).
