  • DML replication with logical log shipping
    Patent number: 9720992
    Abstract: Technologies are described for performing replication within a database environment. For example, replication of database data can be performed using data manipulation language (DML) statements and logical logs. A database node can execute a DML statement, create a logical log comprising the DML statement, and insert the logical log into a logical log queue. The logical log can be sent to one or more other database nodes for execution of the DML statement stored within the logical log. Logical logs can be grouped for sending to other nodes. Logical logs can be executed on a first node and one or more other nodes within the same transaction boundary. Execution of DML statements can be decoupled from sending, receiving, grouping, and/or processing of logical logs.
