Apache Hadoop has gained popularity in the storage, management, and processing of large amounts of data because it can handle large volumes of highly structured data. However, Hadoop cannot handle random high-speed writing and reading and cannot change files without completely rewriting. HBase is a column-based NoSQL Hadoop database that overcomes the shortcomings of HDFS by enabling fast arbitrary writing and reading in an optimized way. In addition, relational databases with exponentially growing data cannot handle various data for better performance. HBase architecture offers scalability and separation for efficient storage and retrieval.
HBase is a data module which provides quick random access to huge amounts of data. It’s a Column Family Oriented NoSQL (Not only SQL) Database which is built on the top of the Hadoop Distributed File System and is suitable for faster reading and writing at large volumes of big data throughput with low I / O latency. Hbase is used for Performance & Scalability. HBase is known for its exceptional scalability because it can handle an increase in load and performance demands by adding various server nodes. This provides optimal performance when consistency is very important and allows developers with modern SQL systems, distributed systems.
Let’s have a look into SQL and NoSQL functionalities:
SQL: Rigid Shema, Consistency, Transactions (Scans every row)
NoSQL: Speed, Flexibility, Scaling (Go directly to Column)
Useful for bulk data
Column Oriented
Document Oriented
Key-Value Store
Graph Oriented
