When To Use Partition Vs Bucketing In Hive. Partitioning helps in elimination of data, if used in where clause, where as bucketing helps in organizing data in each partition into multiple files, so as same set. This blog also covers hive partitioning example, hive bucketing example, advantages and disadvantages of hive partitioning and bucketing. Partitioning in hive is conceptually very simple: Apache hive allows us to organize the table into multiple partitions where we can group the same kind of data. In this tutorial, we are going to cover the feature wise difference between hive partitioning vs bucketing. We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. Hive partitioning separates data into smaller chunks based on a particular column, enhancing query efficiency and data. With partitions, hive divides(creates a directory) the table into smaller parts for every distinct value of a column whereas with bucketing you can specify the number of buckets to create at the time of creating a hive table. In this article, we will see what is partitioning and bucketing, and when to use which one?
