Hive Clustered By Into Buckets. The following is one example of creating a partitioned and. Hive> insert overwrite table test6 select * from test;. In this video, we'll explore how to use hive buckets. Clustered by(user_id) into 256 buckets; Note that we specify a column (user_id) to base the bucketing. In this article, we'll go over what exactly these operations do, what the. In bucketing, hive splits the data into a fixed number of buckets, according to a hash function. 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). Hive buckets provide a way to group data into more manageable chunks for faster querying and processing. Hive> create table test6(x int) clustered by (x) sorted by (x) into 4 buckets; Bucketing, a.k.a clustering is a technique to decompose data into buckets. Hive bucketed table can be created by adding cluster by clause. These are two different ways of physically grouping data together in order to speed up later processing.
