Abstract
Replicating data in a distributed database having a plurality of nodes is disclosed. Replicating includes receiving a semantic command at a local version of the database at a node, interpreting the semantic command, and applying the semantic command to the local version of the database.
Claims29
A method of replicating IP address assignment changes in a distributed database having a plurality of nodes, comprising:
- receiving a semantic command at a first node having a first local version of the database, wherein the semantic command comprises a semantically expressed request to modify one or more IP address assignments in the database that allows for provisional modification of the first local version of the database before sending the semantic command to a master node having a master version of the database;
- provisionally applying the semantic command to the first local version of the database before sending the semantic command to the master node;
- and
- reconciling the semantic command with the master version of the database, wherein reconciling the semantic command with the master version of the database includes determining whether the semantic command includes any IP address assignment changes that would result in an IP address assignment conflict with IP address assignment data stored in the master version of the database on the master node.
A computer program product for replicating IP address assignment changes in a distributed database having a plurality of nodes, the computer program product being embodied in a non-transitory computer readable medium and comprising computer instructions for:
- receiving a semantic command at a first node having a first local version of the database, wherein the semantic command comprises a semantically expressed request to modify one or more IP address assignments in the database that allows for provisional modification of the first local version of the database before sending the semantic command to a master node having a master version of the database;
- provisionally applying the semantic command to the first local version of the database before sending the semantic command to the master node;
- and
- reconciling the semantic command with the master version of the database, wherein reconciling the semantic command with the master version of the database includes determining whether the semantic command includes any IP address assignment changes that would result in an IP address assignment conflict with IP address assignment data stored in the master version of the database on the master node.
A system for replicating IP address assignment changes in a distributed database having a plurality of nodes, comprising:
- a processor configured to:
- receive a semantic command at a first node having a first local version of the database, wherein the semantic command comprises a semantically expressed request to modify one or more IP address assignments in the database that allows for provisional modification of the first local version of the database before sending the semantic command to a master node having a master version of the database;
- provisionally apply the semantic command to the first local version of the database before sending the semantic command to the master node;
- reconcile the semantic command with the master version of the database, wherein reconciling the semantic command with the master version of the database includes determining whether the semantic command includes any IP address assignment changes that would result in an IP address assignment conflict with IP address assignment data stored in the master version of the database on the master node;
- and
- a memory coupled with the processor, wherein the memory provides the processor with instructions.
