Hive Change Number Of Buckets. Learn how to improve query performance in apache hive by implementing data bucketing. If you migrated data from earlier apache hive versions to hive 3, you might need to handle bucketed tables that impact performance. Explore the concept of bucketing, its benefits,. What are the factors to be considered while deciding the number of buckets? One factor could be the block size itself as. In general, the bucket number is determined by the expression hash_function(bucketing_column) mod. 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). Buckets can help with the predicate pushdown since every value belonging to one value will end up in one bucket. Create table [db_name.]newtable (.) [clustered by (col_name, col_name,.) into.
