[jboss-jira] [JBoss JIRA] Commented: (JGRP-1219) S3_PING: generate unique bucket name

    [ https://jira.jboss.org/browse/JGRP-1219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12536023#action_12536023 ] 

Marek Goldmann commented on JGRP-1219:
--------------------------------------

Sounds good, two comments:

- Is there a chance that in one cluster we'll have different JBoss versions? Upgrade? If yes, we need to specify always our own prefix.
- Maybe prefix with "cluster" at the beginning: "cluster-jboss-6-m4", "cluster-jboss-7-ga" would be nicer :)

> The S3 bucket name space is global, therefore collisions between bucket names are likely. To prevent this, generate unique bucket names. This is done as follows:
> - Introduce a new property 'prefix'
> - If null, we use the bucket name as defined by 'location'
> - If not, we list all buckets and pick the first bucket starting with "<prefix>-". This will be the new location
> - If not found, we set location = "<prefix>-<UUID>"
> Prefix could be for example set to "jboss-6-m4" for JBoss6 and to "jboss-7-ga" for JBoss7, then there would not be any collisions between different JBoss versions. The UUID generation makes sure that there are no collisions between bucket names
