Apache Hive Query Patterns: Generalized HiveQL Queries for Common Operations

When developing Hive-based applications, developers always have to deal with different HiveQL queries to perform basic CRUD (Create, Read, Update and Delete) and other operations on Hive table data.

The queries also vary from one application to another. For applications where multiple types of Hive tables are used and many of them are created on the fly during the execution of the application, managing a table’s lifecycle and querying data dynamically become very difficult. Developers have to hardcode various HiveQL queries for each operation. This makes developing, managing and maintaining the application very difficult.
