NoSQL This database management system has been designed in a way that it can store and handle huge amounts of semi-structured or unstructured data. Avro creates binary data which can be both compressed as well as split. Avro creates a file that stores all the data and saves the schema in the metadata section.

Drawback #1: Not Every Database Supports Transaction The relational database support transaction for multiple mutation statements. However, if you use systems like DynamoDB, the transaction support falls under the application or the Data Access Layer. However, Event sourcing comes with a few major limitations.

How HDFS master-slave structure works. A master node called NameNode maintains metadata with critical information, controls user access to the data blocks, makes decisions on replications, and manages slaves. You can change this parameter manually but the system won’t be able to effectively deal with myriads of tiny data pieces.
