Partitioning In Hive Bucketing at Rodney Eubanks blog

Partitioning In Hive Bucketing. 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. Whwenever buckets is used for efficient querying. Partitioning tables changes how hive structures the 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. Partitions is used to organizes tables into partitions. For a faster query response hive table can be partitioned by (country string, dept string). We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. Hive partitions and buckets are the parts of hive data modeling. Partitioning is one of the popular strategies to improve the performance of hive. In this article, we will explore partitioning and bucketing in hive and how they can be implemented using hql. Additionally, you’ll learn how to execute various partition operations including adding, renaming, updating, and deleting partitions.
