Abstract: A system may route incoming data to different data shards using a scalable system architecture. The system may include a data ingestion service, such as a naming service that may input data for you by the system. This data may be routed to specific applications, which may be associated with different shards of the data. The system may decouple data ingestion components from application components to enable adding additional capacity at either end of the system, or anywhere between, to accommodate increases in demand and/or to increase throughput. For example, the system may be modified to add additional data ingestion components without modifying the number of applications components to increase throughput of data ingestion. Similarly, the system may be modified to add application components without modifying the number of data ingestion components to increase throughput of data analysis, for example.
