Partitioning and bucketing in hive are storage techniques to get faster results for the search queries. Present in that partitions can be divided further into buckets. The division is performed based on hash of particular columns that we selected in the table. Clustering aka bucketing on the other hand, will result with a fixed number of files, since you do specify the number of buckets. What hive will do is to take the field, calculate a hash and. 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 problem,. Learn about bucketing vs partitioning. It is used for efficient querying. Partitioning of table data is done for distributing load horizontally. Hive partitions are used to split the larger table into several smaller parts based on one or multiple columns (partition key, for example, date, state e.t.c).
