Abstract

The present disclosure describes a cross cluster failover framework configured to switch a synchronous or asynchronous connection from a first cluster datacenter to a second cluster datacenter based on a health evaluation of the first and second cluster, on an application level, data stream level, or topic level basis. The connections between the first cluster and the consumer application, and second cluster and the consumer application are maintained throughout the failover framework allowing the failover process to be invisible on the consumer application side.

Dependent claims

A distributed data processing system comprising:

a cluster management server configured to communicate with a cluster system comprising a first server cluster and a second server cluster in geographically different regions, the cluster management server comprising a processor and a memory coupled to the processor, the memory storing thereon machine executable instructions that when executed cause the processor to:
determine an initial health status of the first server cluster;
establish a first push connection between a data source and the first server cluster based on a determination that the first server cluster is healthy;
monitor data being transmitted from the data source to the first server cluster, wherein the first server cluster publishes the data to a plurality of data stream categories corresponding to the data;
determine a first cluster health status of the first server cluster for each of the plurality of data stream categories associated with the data source;
determine a second cluster health status of the second server cluster for each of the plurality of data stream categories associated with the data source;
determine the first server cluster is unhealthy for a first data stream category of the plurality of data stream categories associated with the data source;
initiate a failover associated with the first data stream category for the data source, wherein the failover cause the processor to:
establish a second push connection to the second server cluster based on a determination that the second server cluster is healthy for the first data stream category associated with the data source;
and
switch the data source from transmitting to the first server cluster to the second server cluster based on the determination that the first server cluster is unhealthy for the data source and the determination that the second server cluster is healthy for the data source.

A method for cross cluster failover management, the method comprising:

determining, by a cluster management server, an initial first cluster health status of a first server cluster and an initial second cluster health status of a second server cluster;
establishing, by the cluster management server, a first push connection between a data source and the first server cluster based on determining that the initial first cluster health status of the first server cluster is healthy;
monitoring, by the cluster management server, data being transmitted from the data source to the first server cluster, wherein the first server cluster publishes the data to a plurality of data stream categories corresponding to the data;
determining, by the cluster management server, a first cluster health status of the first server cluster for each of the plurality of data stream categories associated with the data source;
determining, by the cluster management server, a second cluster health status of the second server cluster for each of the plurality of data stream categories associated with the data source;
determining, by the cluster management server, the first server cluster is unhealthy for a first data stream category of the plurality of data stream categories associated with the data source;
initiating, by the cluster management server, a failover associated with the first data stream category for the data source, wherein the failover is further comprising:
establishing, by the cluster management server, a second push connection to the second server cluster based on a determination that the second server cluster is healthy for the first data stream category associated with the data source;
switching, by the cluster management server, the data source from transmitting to the first server cluster to the second server cluster based on the determination that the first server cluster is unhealthy for the data source and the determination that the second server cluster is healthy for the data source;
and
maintaining, by the cluster management server, a first pull data connection between the first server cluster and a first application instance, and a second pull data connection between the second server cluster and a second application instance.
