Publication number: 20240104124Abstract: A system, method and computer product for managing distributed transactions of a database. A transaction manager is provided for each of a plurality of transactions of the database. Each transaction manager is configured to perform functions that include generating a transaction token that specifies data to be visible for a transaction on the database. The database contains both row and column storage engines, and the transaction token includes a transaction identifier (TID) for identifying committed transactions and uncommitted transactions.

Patent number: 10824673Abstract: A system includes a non-volatile random access memory storing a column store main fragment of a column of a database table, and a processing unit to read the column store main fragment from the non-volatile random access memory. A volatile random access memory storing a column store delta fragment of the column of the database table may also be included, in which the processing unit is to write to the column store delta fragment. According to some systems, the stored column store main fragment is byte-addressable, and is copied from the volatile random access memory to the non-volatile random access memory without using a filesystem cache.Type: GrantFiled: September 5, 2017Date of Patent: November 3, 2020Assignee: SAP SEInventors: Oliver Rebholz, Ivan Schreter, Abdelkader Sellami, Daniel Booss, Gunter Radestock, Peter Bumbulis, Alexander Boehm, Frank Renkes, Werner Thesing, Thomas Willhalm

Publication number: 20200117733Abstract: A blockchain integration layer uses mappings, for each blockchain of a plurality of blockchains, to integrate blockchain data into a database. A user interface may be presented that allows a user to view the blockchain data from the database, create data for the blockchain in the database, or both. Based on the created data for the blockchain in the database, the blockchain integration layer may modify the blockchain to store the created data. Standardized mappings are used to define the transformations to be used to convert data stored in blockchain blocks into a usable format for external systems. A set of JavaScript object notation (JSON) objects, one for each supported message type, may be used to define the set of transformations to support a blockchain. Using multiple sets of JSON objects, the blockchain integration layer integrates multiple blockchains with the external systems.Type: ApplicationFiled: October 11, 2018Publication date: April 16, 2020Inventors: Kai-Christoph Mueller, Frank Renkes, Brian McKellar

Patent number: 9507810Abstract: A system is described for processing schema updated in a zero-downtime environment. A technique includes establishing an application session to access a database, receiving a schema update, converting the database to an updated database according to the schema update after establishing the application session, generating a temporary compensation view from the schema update, the temporary compensation view containing compensation logic to locate database objects belonging to the database, receiving a database transaction from the application session to access a database object in the database; and processing the compensation logic to locate the database object.Type: GrantFiled: December 10, 2013Date of Patent: November 29, 2016Assignee: SAP SEInventors: Stefan Baeuerle, Wolfgang Lehner, Anil Kumar Goel, Frank Renkes, Joydeep Das

Patent number: 9336262Abstract: A system, method and computer product for accelerating parallel database transactions. One or more data processors execute a first transaction on a database. The first transaction includes a transactional lock associated with each of one or more records to update the one or more records during the first transaction, and a pre-commit command to request acknowledgement of committing the updating of the one or more records during the first transaction. The one or more data processors execute a second transaction on the database in parallel with the first transaction. The second transaction includes a transactional lock associated with each of one or more records to update the one or more records during the second transaction, and a pre-commit command to request acknowledgement of committing the updating of the one or more records during the second transaction. The transactional locks of the first and second transactions are released before flushing log records associated with the first and second transactions.Type: GrantFiled: October 5, 2010Date of Patent: May 10, 2016Assignee: SAP SEInventors: Juchang Lee, Frank Renkes, Sangyong Hwang

Patent number: 9122738Abstract: Methods and apparatus, including computer program products, for selection of rows and values from indexes with updates. In general, rows of an index may be associated with validity flags that indicate whether a row has been updated with an update inserted in a delta index; one scheme for value identifiers may be used for an index and another scheme for one or more delta indexes where all of the indexes are, to at least some extent, compressed according to dictionary-based compression; and multiple delta indexes may be used in alternation such that one delta index may accept updates while another is being updated. The delta indexes may also have validity flags and all updates, such as modifications of values, deletion of records, and inserting of new records may be handled as updates accepted by one or more delta indexes.Type: GrantFiled: April 12, 2013Date of Patent: September 1, 2015Assignee: SAP SEInventors: Frank Renkes, Thomas Peh, Andrew Ross, Holger Schwedes, Wolfgang Stephan

Patent number: 8868512Abstract: According to some embodiments, a column-oriented in-memory database structure may be established. The database structure may, for example, include a main store and a dictionary compressed delta store. Moreover, the delta store may comprise a value identifier vector and a delta dictionary associated with a column of the database. A transaction associated with the column may then be received and recorded within the delta store. According to some embodiments, entries associated with the transaction may be added to a value log of the value identifier vector and, independently, to a dictionary log of the delta dictionary.Type: GrantFiled: December 29, 2011Date of Patent: October 21, 2014Assignee: SAP SEInventors: Frank Renkes, Joos-Hendrik Bose

Patent number: 8806422Abstract: Local dependency metadata can be collected from local metadata repositories of a plurality of development systems in a layered development system landscape, and a global where-used list that includes intra-layer and inter-layer dependencies between development entities in a layered development system landscape can be created, for example by aggregating the collected local dependency data. A usage metric quantifying how frequently each development entity is depended upon by other development entities in the layered development system landscape can be assigned to each development entity in the layered development system landscape. A measure of a relative effect of a change to one of the development entities on other development entities in the layered development system landscape can be promoted.Type: GrantFiled: October 27, 2011Date of Patent: August 12, 2014Assignee: SAP AGInventors: Frank Brunswig, Udo Klein, Michael Meyringer, Tim Gaiser, Holger Handel, Frank Renkes
