Yes, Hbase is known to be a column oriented database (where the column data stay together), the data in HBase for a particular row stay together and the column data is spread and not together.
In HBase the cell data in a table is stored as a key-value pair where you can have any number of columns (keys), each of which has a value, which is stored in HDFS. column families allow you to host multiple key/value maps in the same row. Some of the factors that matters regarding column oriented are:
- Retrieval of a few columns from a table with many columns will be faster.
- Aggregate calculation of single column will be fast.
