Patent number: 11681684Abstract: Technologies are described for facilitating transaction processing in a distributed database environment. A database client sends database operations to a slave node, which mediates execution of the transaction. A connection between the database client and the slave node is associated with an identifier, and the transaction has an identifier. The database client sends a commit request to a master node over a network connection between the master node and the database client. The commit request includes the transaction identifier. The commit request can also include an indication of database nodes executing operations in the transaction.Type: GrantFiled: January 15, 2021Date of Patent: June 20, 2023Assignee: SAP SEInventors: Juchang Lee, Deok Koo Kim, Chang Gyoo Park, Nosub Sung
