Thanks Filippo. I think I figured out now what was going wrong. I was confused between the shardId and the entityId.
shardId == context().parent().path().name() entityId == self().parth().name() My entities were being created again and again because I was computing the entityId wrongly. In my case, all messages carry an id. What I need is entityId = hash(messageId) and shardId = hash(entityId). However, I was doing entityId = messageId and shardId = hash(messageId). Therefore I was always creating a new entity because the messageId is unique. I've fixed my MessageExtractor now and everything goes as it should. thanks, Bert On Thursday, February 11, 2016 at 5:36:17 PM UTC+1, Bert Robben wrote: > > Hi, > > I'm trying to use sharding and that works reasonably well (my entities are > being created across my cluster and they respond to my requests). > > However, I notice that after each call to my entity, it is destroyed. > Every next call on the entity then recreates it.
