Lambda+: Cassandra and Spark for Scalable Architecture

Many of you have heard of and a few of you may have used the Lambda Architecture. If you've not heard of it the name doesn't communicate a lot. In short the Lambda Architecture has 3 primary components with a 2 pronged approach to analytics:

1. Speed Layer: Records are analyzed as they're created in the Speed Layer.
2. Batch Layer will run the same analytics as the Speed Layer but on all records with a database designed for this type of work such as ElephantDB.
3. A Serving Layer will read data from the Speed Layer and data from the Batch Layer. If there is a disagreement on the same records, then data from the Batch Layer will be treated as authoritative.
