Jonathan Ellis reassigned CASSANDRA-7839: ----------------------------------------- Assignee: Carl Yeksigian > Support standard EC2 naming conventions in Ec2Snitch > ---------------------------------------------------- > > Key: CASSANDRA-7839 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7839 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Gregory Ramsperger > Assignee: Carl Yeksigian > Attachments: conditionally-use-full-Amazon-style-naming-for-dc.patch > > > The EC2 snitches use datacenter and rack naming conventions inconsistent with > those presented in Amazon EC2 APIs as region and availability zone. A > discussion of this is found in CASSANDRA-4026. This has not been changed for > valid backwards compatibility reasons. Using SnitchProperties, it is possible > to switch between the legacy naming and the full, AWS-style naming. > Proposal: > * introduce a property (ec2_naming_scheme) to switch naming schemes. > * default to current/legacy naming scheme > * add support for a new scheme ("full") which is consistent AWS conventions > ** data centers will be the region name, including the number > ** racks will be the availability zone name, including the region name > Examples: > * * legacy* : datacenter is the part of the availability zone name preceding > the last "\-" when the zone ends in \-1 and includes the number if not \-1. > Rack is the portion of the availability zone name following the last "\-". > ** us-west-1a => dc: us-west, rack: 1a > ** us-west-2b => dc: us-west-2, rack: 2b; > * *full* : datacenter is the part of the availability zone name preceding > zone letter. rack is the entire availability zone name. > ** us-west-1a => dc: us-west-1, rack: us-west-1a > ** us-west-2b => dc: us-west-2, rack: us-west-2b; -- This message was sent by Atlassian JIRA (v6.2#6252)
