Databus consumer group maintains the offsets in property store. It provides a key value interface.
http://helix.apache.org/javadocs/0.6.4/reference/org/apache/helix/store/package-summary.html See HelixPropertyStore api, http://helix.apache.org/javadocs/0.6.4/reference/org/apache/helix/store/HelixPropertyStore.html The base class for this is http://helix.apache.org/javadocs/0.6.4/reference/org/apache/helix/BaseDataAccessor.html Entire Helix library uses this api underneath and property store is a place where application can store additional information, subscribe to the changes (recursively). When you subscribe(optional) to changes all values are cached locally and updated on change. We really need a usage doc for property store api. thanks, Kishore G On Tue, Mar 10, 2015 at 1:45 PM, Vinoth Chandar <[email protected]> wrote: > Hi, > > I am writing something very similar to the RabbitMQ Consumer group recipe. > I would like to be able to remember a number/offset for each partition in > the resource.
