How To Create Bucket In Hive. In hive, we have to enable buckets by using the set.hive.enforce.bucketing=true;. The bucketing in hive is a data organizing technique. Buckets use some form of hashing algorithm at back end to read each record and place it into buckets; Hive facts creating bucketed table in hive. We can specify bucketing with cluster by clause. We need to specify the clustered by clause as well as into buckets to create bucketed table. In apache hive, for decomposing table data sets into more manageable parts, it uses hive bucketing concept. Apache hive allows us to organize the table into multiple partitions where we can group the same kind of data together. We can specify the number of buckets that we. It is similar to partitioning in hive with an added functionality that it divides. However, there are much more to learn about bucketing in hive. 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). It is used for distributing the load horizontally. Let us create a bucketed table in a hive.
