Logical Representation of Distributed Database Table Updates in an Append-Only Log File

摘要

A method implemented by a computer network includes receiving a database table update to a distributed database. The database table update is loaded into a database table partition on a node of a computer network executing the distributed database. The database table update is added to an append-only log file corresponding to the database table partition. The added update represents data associated with the database table update in a logical representation that is independent of the physical representation of the data at the node. This facilitates transferring the database table partition to other nodes within the computer network.
