How To See Buckets In Hive. With bucketing, we can tell hive group data in few “buckets”. Bucketing is an approach for improving hive query performance. Present in that partitions can be divided further into buckets It is used for efficient querying. Hive writes that data in a single file. Bucketing stores data in separate files, not separate subdirectories like. And when we want to retrieve that data, hive knows which partition to check and in which bucket that data is. However, there are much more to learn about bucketing in hive. In general, the bucket number is determined by the expression hash_function (bucketing_column) mod num_buckets. The bucketing in hive is a data organizing technique. It is similar to partitioning in hive with an added functionality that it divides large datasets into more manageable parts known as 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). In apache hive, for decomposing table data sets into more manageable parts, it uses hive bucketing concept.
