HQL is Hive Query Language, similar to that of MySQL database. It performs operations such as read, write, and manage big data tables and store them in HDFS or any other data sources through Data Definition Language (DDL), Data Manipulation Language (DML), and user-defined functions to query, process, mine and report the data.

SQL codes are lengthier than HQL; however, SQL is faster than non-native HQL, but HQL can operate as quickly as SQL if the cache size is set right. SQL relational database model, but HQL is a combination of object-oriented programming with the relational database. SQL manipulates data in the tables and modifies it.

Partitioning in Hive is dividing the table into different parts based on the values in a specific column. This is done to organize the tables. Also, it is easier to query a portion of data using partitioning. The columns are partitioned based on values such as date, department, city, etc.

Different types of partitioning in Hive are Dynamic partitioning and Static partitioning. Dynamic partitioning is used when a single insert is given to the partition table, and it loads the data from a non-partitioned table. It takes a little longer than static partitioning to load the data. Also, dynamic partitioning is suitable when massive amounts of data are stored in the table.
