This session will cover KomodoHealth's initiative around exploring healthcare data in Apache Ignite. It will provide quick overview of KomodoHealth's current architecture in terms of claims data ingestion, processing and end user/application usage. It will go over why we needed to evaluate distributed in-memory solutions. The main focus afterwards will be on our prototype initiative around testing in single instance, four node small instances and ultimately TB scale cluster. We will talk through issues we encountered in setting up the cluster, how we loaded data, query performances, partitions, indexes, etc.
