What Is Partitioning And Bucketing In Hive. in this article, we will see what is partitioning and bucketing, and when to use which one? bucketing is another technique for decomposing data sets into more manageable parts. For example, suppose a table using date as the top. hive partitioning separates data into smaller chunks based on a particular column, enhancing query. We define one or more columns to partition the data on, and then for each unique combination. partitioning in hive is conceptually very simple: hive bucketing is a way to split the table into a managed number of clusters with or without partitions. Additionally, you’ll learn how to execute various partition operations including adding, renaming, updating, and deleting partitions. 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.
