An attempt to answer one question which all people trying to pick a front end framework has . Is Angular or React the right choice ?

Once I started using Typescript I could see some clear advantages and choice for strong typing which was missing in Javascript for long was being enforced. Of course I
Lambda is a most discussed architecture pattern in data science space .The below is an attempt to explain it . Lambda is a data processing architecture and framework designed to address robustness and scalability and fault tolerance of big data systems. In this study we are planning to focus on the batch and speed layers to achieve data processing. As proposed in the summary for both the batch and stream we will be using Spark. What constitutes the lambda architecture for data processing? Lambda is a architecture pattern . Here the architecture we investigate has Lambda implemented primarily with Spark for batch and stream processing, Cassandra for No -SQL database storage, Kafka for accessing and sending the stream data and Zeppelin for visualizations. Sample application workflow investigated - In this sample application Spark is used for both batch and real time. We will persist the data in HDFS to perform batch operations against it. [HD
