HBase

HBase is a column-based distributed storage system that features high reliability, performance, and scalability. HBase is designed to break through limitations of a relational database to process massive amounts of data.

Application scenarios of HBase have the following features:

Massive data processing (higher than the TB or PB level)
High throughput
Highly efficient random read of massive data
Excellent scalability
Capable of concurrently processing structured and unstructured data
Not all Atomicity, Consistency, Isolation, Durability (ACID) features supported by traditional relational databases are required.
HBase tables have the following features:
- Large: One table contains hundreds of millions of rows and millions of columns.
- Column-based: Storage and rights control is implemented based on columns (families), and columns (families) are independently retrieved.
- Sparse: Null columns do not occupy storage space, so a table can be sparse.

API Types

You are advised to use Java to develop HBase applications, because HBase is developed based on Java and Java is concise, universal, and easy-to-understand.

HBase adopts the same Application Programming Interfaces (APIs) as those of Apache HBase. For details about the APIs, visit http://hbase.apache.org/apidocs/index.html.

Table 1 describes the functions that HBase can provide by invoking APIs.
