-----------------------------------------
Labels: CEP-53 (was: )
> Support coordination for cluster-wide operations in operational job framework
> ------------------------------------------------------------------------------
>
> Key: CASSSIDECAR-371
> URL: https://issues.apache.org/jira/browse/CASSSIDECAR-371
> Project: Sidecar for Apache Cassandra
> Issue Type: Improvement
> Reporter: Andrés Beck-Ruiz
> Priority: Major
> Labels: CEP-53
>
> The operational job framework currently only supports local jobs on nodes
> that a Sidecar instance manages. In order to perform multi-node, up to
> cluster-wide operations on Cassandra clusters, we need to add a coordination
> interface.
> In the default implementation, the {{StorageOperationalJobCoordinator}} will
> be used for coordination. This coordinator will use the {{StorageProvider}}
> to set new operational jobs as active and ensure that a single operational
> job is running at the same time. Other implementations of an operational job
> coordinator can use different methods for setting operational jobs as active
> and coordinating local node jobs between Sidecar instances.
> This ticket also tracks the work to introduce a {{LocalJob}}, which are jobs
> on local nodes that make up a larger operational job. For example, restarting
> a three node cluster would result in one operational job and three local
> jobs, one for each node. The {{LocalJobCoordinator}} will be responsible for
> polling the {{StorageProvider}} for new operational jobs, and the
> {{LocalJobManager}} will create a {{LocalJob}} once it is the Sidecar
> instance’s turn to execute an operation on a local node.
