[jira] [Commented] (JCLOUDS-581) Method calls "startNodesMatching" and "stopNodesMatching" added to BaseComputeService

["Ignasi Barrera (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCLOUDS-581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14017143#comment-14017143 ] 

Ignasi Barrera commented on JCLOUDS-581:
----------------------------------------

The portable {{ComputeService}} does not provide a {{start}} or {{stop}} operation. Instead, the available operations are [suspendNode|https://github.com/jclouds/jclouds/blob/master/compute/src/main/java/org/jclouds/compute/ComputeService.java#L203-L229] and [resumeNode|https://github.com/jclouds/jclouds/blob/master/compute/src/main/java/org/jclouds/compute/ComputeService.java#L178-L201].

jclouds maps the different provider specific states of the nodes to the portable [NodeMetadata#Status|https://github.com/jclouds/jclouds/blob/master/compute/src/main/java/org/jclouds/compute/domain/NodeMetadata.java#L34-L60] ones, and the operations the {{ComputeService}} exposes follow the semantics of the latter states. Each provider implements those methods according to the provider specific capabilities, so in some providers a "suspend" operation might be a real "stop" operation in the provider api, or a "pause", etc. It is up to the provider to provide the particular implementation.

In favor of portability, the ComputeService exposes those two calls. Aren't those enough for your use case?

> Addition of methods "startNodesMatching" and "stopNodesMatching" added to BaseComputeService. We are coding this very thing on our end for openstack/rackspace but seems a fairly common enough thing that all providers and/or users of jclouds could take advantage of.
