Method for creating a database clone of a distributed database, system for creating a database clone of a distributed database, program and computer program product
The invention relates to a method for creating a database clone of a distributed database, wherein the distributed database is stored on source nodes of a computer network, wherein the distributed database comprises a set of data items being distributed across the source nodes, wherein a first data item of the set of data items is stored on a first node of the source nodes, wherein the method comprises the steps of: -- coupling collector nodes to the computer network, wherein the collector nodes comprise a second node, -- starting a cloning process, wherein the cloning process includes: -- creating, on the second node, a copy of the first data item of the first node, -- updating, in a transaction step, the first data item of the first node, -- transmitting, to the second node storing the copy of the first data item, transaction data related to the transaction step, wherein the transaction data is stored on the second node, and/or updating the copy of the first data item being stored on the second node, -- completing the cloning process such that a complete copy of the set of data items of the source nodes is stored on the collector nodes.
