Abstract

A method, computer program product, and computer system for receiving a change to a configuration parameter associated with a first cluster node in a cluster configuration. The configuration parameter may be stored in a shared cluster memory. The configuration parameter may be distributed from the shared cluster memory to the cluster configuration.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving a change to a configuration parameter associated with a first cluster node of a plurality of cluster nodes in a cluster configuration, wherein the cluster configuration includes one or more configuration clients and one or more configuration API endpoints, wherein the one or more configuration clients and the one or more configuration API endpoints include a configuration client library, wherein the change to the configuration parameter includes a parameter update respective to an assumption about an application, wherein the parameter update respective to the assumption about the application includes at least one of an increase limit and a decrease limit respective to object creation, wherein the cluster configuration is organized as a tree structure, wherein receiving the change to the configuration parameter includes splitting the tree structure by the configuration parameter relative to a corresponding dimension, wherein the corresponding dimension includes at least one of a logical dimension and a physical dimension, wherein at least two different cluster nodes of the plurality of cluster nodes are configured for triggering at least two different state transitions at the same time, wherein triggering the at least two different state transitions includes:
registering a client-specified listener with the configuration client library;
sending a signal to the configuration client library to effectuate a snapshot of the cluster configuration;
calling, via the configuration client library, the client-specified listener to facilitate one or more cluster configuration changes; and
notifying the one or more configuration clients of the one or more cluster configuration changes;

storing, via the configuration client library of at least one of the one or more configuration clients and the one or more configuration API endpoints, the configuration parameter in a shared cluster memory; and
distributing the configuration parameter from the shared cluster memory to the cluster configuration.

2. The computer-implemented method of claim 1 wherein the configuration parameter includes at least one of a mode, a state, and a numerical parameter of at least one storage service running on the first cluster node.

3. The computer-implemented method of claim 1 wherein the cluster configuration is shown as a single view for each storage service running on the plurality of cluster nodes in the cluster configuration.

4. The computer-implemented method of claim 1 wherein a configuration update is applied to the plurality of cluster nodes in the cluster configuration.

5. The computer-implemented method of claim 4 wherein the configuration update is limited to the first cluster.

6. The computer-implemented method of claim 4 wherein the configuration update is limited to a single replication group.

7. The computer-implemented method of claim 1 wherein storing the configuration parameter in the shared cluster memory includes maintaining a list of one or more overridden configuration parameters resulting from splitting the tree structure by the configuration parameter relative to the corresponding dimension.

8. A computer program product residing on a non-transitory computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, cause at least a portion of the one or more processor to perform operations comprising:
receiving a change to a configuration parameter associated with a first cluster node of a plurality of cluster nodes in a cluster configuration, wherein the cluster configuration includes one or more configuration clients and one or more configuration API endpoints, wherein the one or more configuration clients and the one or more configuration API endpoints include a configuration client library, wherein the change to the configuration parameter includes a parameter update respective to an assumption about an application, wherein the parameter update respective to the assumption about the application includes at least one of an increase limit and a decrease limit respective to object creation, wherein the cluster configuration is organized as a tree structure, wherein receiving the change to the configuration parameter includes splitting the tree structure by the configuration parameter relative to a corresponding dimension, wherein the corresponding dimension includes at least one of a logical dimension and a physical dimension, wherein at least two different cluster nodes of the plurality of cluster nodes are configured for triggering at least two different state transitions at the same time, wherein triggering the at least two different state transitions includes:
registering a client-specified listener with the configuration client library;
sending a signal to the configuration client library to effectuate a snapshot of the cluster configuration;
calling, via the configuration client library, the client-specified listener to facilitate one or more cluster configuration changes; and
notifying the one or more configuration clients of the one or more cluster configuration changes;

storing, via the configuration client library of at least one of the one or more configuration clients and the one or more configuration API endpoints, the configuration parameter in a shared cluster memory; and
distributing the configuration parameter from the shared cluster memory to the cluster configuration.

9. The computer program product of claim 8 wherein the configuration parameter includes at least one of a mode, a state, and a numerical parameter of at least one storage service running on the first cluster node.

10. The computer program product of claim 8 wherein the cluster configuration is shown as a single view for each storage service running on the plurality of cluster nodes in the cluster configuration.

11. The computer program product of claim 8 wherein a configuration update is applied to the plurality of cluster nodes in the cluster configuration.

12. The computer program product of claim 11 wherein the configuration update is limited to the first cluster.

13. The computer program product of claim 11 wherein the configuration update is limited to a single replication group.

14. The computer program product of claim 8 wherein storing the configuration parameter in the shared cluster memory includes maintaining a list of one or more overridden configuration parameters resulting from splitting the tree structure by the configuration parameter relative to the corresponding dimension.

15. A computing system including one or more processors and one or more memories configured to perform operations comprising:
receiving a change to a configuration parameter associated with a first cluster node of a plurality of cluster nodes in a cluster configuration, wherein the cluster configuration includes one or more configuration clients and one or more configuration API endpoints, wherein the one or more configuration clients and the one or more configuration API endpoints include a configuration client library, wherein the change to the configuration parameter includes a parameter update respective to an assumption about an application, wherein the parameter update respective to the assumption about the application includes at least one of an increase limit and a decrease limit respective to object creation, wherein the cluster configuration is organized as a tree structure, wherein receiving the change to the configuration parameter includes splitting the tree structure by the configuration parame
