Class CloudStoreSeedNodeProvider

java.lang.Object

io.hekate.cluster.seed.jclouds.CloudStoreSeedNodeProvider

All Implemented Interfaces:

io.hekate.cluster.seed.SeedNodeProvider, io.hekate.core.report.ConfigReportSupport

public class CloudStoreSeedNodeProvider
extends Object
implements io.hekate.cluster.seed.SeedNodeProvider, io.hekate.core.report.ConfigReportSupport

Cloud store-based implementation of SeedNodeProvider interface.

This provider uses a cloud storage (f.e. Amazon S3) to keep track of active seed nodes.

When provider starts discovering other nodes it uses BlobStore to creates a new empty blob whose name contains local node's host address and port. Such blob is stored in a configurable container (aka bucket) under /[namepsace]/ folder. In order to find other seed nodes it reads the list of all blobs in that folder and parses addresses from their names.

Please see the documentation of CloudStoreSeedNodeProviderConfig class for details about the available configuration options.
