Can you briefly explain all the available components of Hive Data Model?

Answer»

The available components of HIVE Data Model are as below:

  • TABLES: These tables are similar to RDBMS. Joins and unions can be used on tables. All the table data is STORED in HDFS. We can also apply filters in tables.  
  • Partitions: We can actually specify partition keys in each table to determine how data is getting stored. Using partitions, we can specify what datasets can be looked upon rather than the whole table.
  • Buckets: Data can be divided into buckets in each partition. We can easily evaluate QUERIES BASED upon some specific sample data with the help of buckets.
