Use Of Buckets In Hive. Bucketing in hive is the concept of breaking data down into ranges, which are known as buckets, to give extra structure to the data so it may be used for more efficient queries. With bucketing, we can tell hive group data in few “buckets”. Partitioning in hive is conceptually very simple: We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. However, there are much more to learn about bucketing in hive. Hive writes that data in a single file. If you migrated data from earlier apache hive versions to hive 3, you might need to handle bucketed tables that impact performance. In apache hive, for decomposing table data sets into more manageable parts, it uses hive bucketing concept. Learn how to improve query performance in apache hive by implementing data bucketing. Explore the concept of bucketing, its benefits,. And when we want to retrieve that data, hive knows which partition to check and in which bucket that data is. 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).
