Nosql Questions
Horizontal partitioning in NoSQL databases refers to the practice of splitting a large dataset across multiple nodes or servers. Each node or server contains a subset of the data, allowing for parallel processing and improved scalability. This partitioning is typically based on a specific criterion, such as a range of values or a hash function.
On the other hand, vertical partitioning in NoSQL databases involves splitting a dataset based on the attributes or columns of the data. Instead of distributing the data across multiple nodes, vertical partitioning focuses on dividing the attributes of a single record or document. This partitioning strategy is useful when certain attributes are accessed more frequently than others, allowing for better performance optimization.
In summary, horizontal partitioning divides the data across multiple nodes or servers, while vertical partitioning splits the attributes or columns of a single record or document. Both techniques aim to improve scalability, performance, and manageability in NoSQL databases.
