In this presentation, we would like to share our experience in using Apache Ignite as a NoHadoop platform to develop a web service for distributed monitoring and processing of data generated by wearable Holter ECG devices. The purpose of monitoring is early diagnosis and notification about patients with urgent cardiac conditions. The presentation provides the alternative to Hadoop ecosystem for processing large amounts of data. Its main auditory are BigData specialists. Also the presentation may be useful to anyone who is interested in machine data learning algorythms that are applied to medical data.
