Data Storage: The next step after data ingestion is to store it in HDFS or a NoSQL database such as HBase. Typically, data processing is done using frameworks such as Hadoop, Spark, MapReduce, Flink, and Pig, to mention a few. How is Hadoop related to Big Data? How is Hadoop related to Big Data?

They tackled the topic, “SQL versus NoSQL Databases in the Modern Data Stack.” I remember back in the day when you had to set up your clusters and run Hadoop and Kafka clusters on top, it was quite expensive. Now, we don’t have to care about bytes, but we do have to care about how many gigabytes or terabytes we are going to process.
