What Are Buckets In Hive at Ed Butler blog

What Are Buckets In Hive. Buckets use some form of hashing algorithm at back end to read each record and place it into 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. 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). That technique is what we call bucketing in hive. Based on your partition clause, for each partition will have 32 buckets created. Bucketing is a very similar concept, with some important differences. A hive table can have both partitioning and bucketing. Data bucketing is a technique used to organize data in a distributed system, such as apache hive, to improve query performance. Here, we split the data into a fixed number of buckets, according to a hash function over some set of. Basically, for decomposing table data sets into more manageable parts, apache hive offers another technique.
