Hive Partitions And Buckets at Seth Scutt blog

Hive Partitions And Buckets. Partition is helpful when the table has one or more partition. In this article, we will see what is partitioning and bucketing, and when to use which one? 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. Partitioning in hive is conceptually very simple: Hive partitions is a way to organizes tables into partitions by dividing tables into different parts based on partition keys. Learn how to create, show, add, rename, update, and drop partitions in hive tables using sql commands and hdfs operations. Partitions are a way to split large tables into smaller logical tables based on one or more columns. We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. Apache hive allows us to organize the table into multiple partitions where we can group the same kind of data together. We have taken a brief look at what is hive partitioning and what is hive Hive bucketing is a way to split the table into a managed number of clusters with or without partitions. Comparison between hive partitioning vs bucketing. 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.
