Class SimpleDBConfigSource

java.lang.Object

com.netflix.priam.configSource.AbstractConfigSource

com.netflix.priam.configSource.SimpleDBConfigSource

All Implemented Interfaces:

IConfigSource

public final class SimpleDBConfigSource
extends AbstractConfigSource

Loads config data from SimpleDB. initialize(String, String) will query the SimpleDB domain "PriamProperties" for any potential configurations. The domain is set up to support multiple different clusters; this is done by using amazon's auto scaling groups (ASG).

Schema

• "appId" // ASG up to first instance of '-'. So ASG name priam-test will create appId priam, ASG priam_test will create appId priam_test.
• "property" // key to use for configs.
• "value" // value to set for the given property/key.
• "region" // region the config belongs to. If left empty, then applies to all regions.
