In simple terms, MongoDB replication is the process of creating a copy of the same data set in more than one MongoDB server. This can be achieved by using a Replica Set. A replica set is a group of MongoDB instances that maintain the same data set and pertain to any mongod process....
MongoDB Data Model Storage Cluster Architecture Replic Set Sharding Summary Introduction Just like Internet, Big Data is part of our lives today. From search, online shopping, video on demand, to e-dating, Big Data always plays an important role behind the scene. Some people claim that Intern...
Sometimes, your data or processing tasks are not easily or efficiently represented using the file and directory model of storage. Examples of this include collections of key-values or large sparse tables. (NoSQL for non-files) NoSQL projects such as Cassandra, MongoDB, and HBase handle these...
MongoDB is another popular NoSQL database that is often compared to Apache Cassandra. While both databases are designed to handle large volumes of unstructured data, they have some key differences. Scalability:Both Apache Cassandra and MongoDB are designed to scale horizontally, but Cassandra is kn...
It is efficient, and it automatic distributes the data and work across the machines and in turn, utilizes the underlying parallelism of the CPU cores. Hadoop does not rely on hardware to provide fault-tolerance and high availability (FTHA), rather Hadoop library itself has been designed to ...
New cloud storage service functionality for easy access to image and vector data in cloud services. Enhanced database management with new transaction management and user management capabilities. Supports databases such as PostGIS, Oracle, MongoDB, Alibaba PolarDB, Huawei GaussDB, etc. ...
MongoDB isschema-less,enabling you to persist objects in a flexible wayand, thus, adapt quickly to changes in requirements. Plus, it’s highlyscalableandbased on map-reduce, making it suitable for big data applications. MongoDB is so flexible that it can be used as a schema-less document...
The six shards below contain partitionable data. Each of the shards is federated with all knowledge bases. Queries are run in parallel on each of the federations. The black lines show how each shard is federated with the knowledge bases. ...

Maybe your data is already available in a flat file or XML format and you want a database that can use XML files, like MongoDB. Or, you might prefer the approach and packages available in Python to those found in PHP. Each system has its particular streng...
