Stratio is a big data platform that can combine stored and streaming data in real-time queries in less than 30 seconds. It uses Spark over Cassandra and MongoDB for processing. The platform provides tools like Spark Streaming, SQL (Shark), machine learning (MLLib), and graph processing (GraphX). Complex event processing (CEP) can analyze and correlate events from multiple sources to detect more complex patterns. Stratio Streaming provides a CEP engine with operators like filter, join, aggregation, and pattern/sequence processing over event streams. The platform also includes tools for easily designing extraction, transformation, and loading (ETL) workflows with Stratio Ingestion, which is based on Apache Flume.
