Add Partition Hive Example. Partitioning is a method of dividing a table. The table contains client detail like id, name, dept, and. Now let’s understand data partitioning in hive with an example. Hive is a data warehouse infrastructure built on top of hadoop that provides data summarization, querying, and analysis. At a high level, hive partition is a way to split the large table into smaller tables based on the values of a column (one partition for each distinct values) whereas bucket is a technique to divide the data in a manageable form (you can specify how many buckets you want). Tables in apache hive are partitioned similarly to sql. Let’s create a partition table and load the csv file into it. To create a hive table with partitions, you need to use partitioned by clause along with the column you wanted to partition and its type. Consider a table named tab1. You can add partition without specifying full path:
