There are some operations that can be performed on HBase data; these are known as HBase data model operations. These operations might have tasks such as reading from, writing to, and modifying data into HBase. Now, we will see the following data model operations:
Read operations using
Get()andScan()Write operations using
Put()Modify operations using
Delete()
In this section, we will see the data models that are useful to read data from an HBase table.
Get() reads a row from a table. It can read a single or a set of rows based on the specified condition. It returns a result that contains data in key-value pairs or a map format. This method is provided by HTable classes and executed as HTable.get (condition). It returns a row specified as a row key or one that's based on a matching filter.
