Decide Number Of Buckets In Hive. 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). 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. By implementing bucketing, you can achieve faster query execution, efficient data retrieval, and optimized analysis of large datasets in apache. One factor could be the block size itself as. What are the factors to be considered while deciding the number of buckets? The key observation is that because the number of buckets is fixed (per partition), having a large number of distinct values in the bucketing columns is not a. As part of this video we are learningwhat is bucketing in hive and sparkhow to create.
