Hive Bucketing Multiple Columns at Salvador Simpson blog

Hive Bucketing Multiple Columns. For example, lets say that the table has. bucketing gives one more structure to the data so that it can used for more efficient queries. A table is bucketed on one or more columns with a fixed. We define one or more columns to partition the data on, and then for each unique combination. Bucketing segregates records into a number of files or buckets. what does it mean to have the clustered by on more than one column? Bucketing is usually applied to columns that have a very high number of unique values. partitioning in hive is conceptually very simple: The range for a bucket is determined by the hash value of one. hive bucketing is a simple form of hash partitioning. 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). Use multiple columns as bucketing columns to achieve better distribution. bucketing is another strategy used for performance improvement in hive.
