What Is Hash Function In Bucketing In Hive at Edward Baehr blog

What Is Hash Function In Bucketing In Hive. Here, we split the data into a fixed number of buckets, according to a hash function over some set of columns. The hash_function depends on the type of the bucketing column. For an int, it's easy, hash_int(i) == i. Where the hash_function depends on the type of the bucketing column. The number of buckets is determined by hashfunction(bucketingcolumn) mod. Along with mod (by the total number of buckets). When inserting records into a hive bucket table, a bucket number will be calculated using the following algorithym:. Hive partitioning separates data into smaller chunks based on a particular column, enhancing query efficiency and data. Here, modules of current column value and the number of required buckets is calculated. For example, if user_id were an. The way bucketing actually works is : Bucketing is a very similar concept, with some important differences. Basically, this concept is based on hashing function on the bucketed column. The concept of bucketing is based on the hashing technique.
