Abstract: Examples include a multi-node cluster having a node with a clustering layer. The clustering layer may be located between an application programming interface (API) layer and a service layer and the multi-node cluster may be associated with a database. In some examples, the clustering layer may discover whether a number of nodes associated with the multi-node cluster has changed. Based, at least in part, on the determination that the number of nodes associated with the multi-node cluster has changed, at the clustering layer, the database may be sharded and a new API call may be issued to the API layer.
