接口 RefreshHandler

所有已知实现类:

ContinuousRefreshHandler

@PublicEvolving
public interface RefreshHandler

This interface represents the meta information of current materialized table background refresh pipeline. The refresh mode maybe continuous or full, the meta information in the two modes is not consistent, so user need to implementation this interface according to different case.

In continuous mode, the meta information maybe contains { "clusterType": "yarn", "clusterId": "xxx", "jobId": "yyyy" }.

In full mode, the meta information maybe contains { "endpoint": "xxx", "workflowId": "yyy" }. Due to user may use different workflow scheduler in this mode, user should implement this interface according to their plugin.

This interface will be serialized to bytes by RefreshHandlerSerializer, then store to Catalog for further operation.
