Hive Number Of Buckets. What are the factors to be considered while deciding the number of buckets? 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). One factor could be the block size itself as each bucket is a. I think if you bucket on all the keys (with ~40 buckets) you will get the most speed improvement, but this is just a theoretical guess. (when using both partitioning and bucketing, each partition will be split into an equal number of buckets.) hive will guarantee that all rows which have the same hash will end up in the. Clustering, aka bucketing, will result in a fixed. Explore the concept of bucketing, its benefits, bucketing. Learn how to improve query performance in apache hive by implementing data bucketing. Bucketing is another way for dividing data sets into more manageable parts. In general, the bucket number is determined by the expression hash_function (bucketing_column) mod num_buckets.
