When To Use Bucketing And Partitioning In Hive. These are two different ways of physically grouping data together in order to speed up later processing. Hive bucketing is a way to split the table into a managed number of clusters with or without partitions. With partitions, hive divides (creates a directory) the table into smaller parts for every distinct value of a column whereas with bucketing you can specify the number of buckets to create at the time of creating a hive table. In this article, we'll go over what exactly these operations do, what the. Apache hive allows us to organize the table into multiple partitions where we can group the same kind of data together. Using partition we can make it faster to do queries on slices of the data. If you need to partition by a column with a high number of distinct values, consider using bucketing. Hive partitioning separates data into smaller chunks based on a particular column, enhancing query efficiency and data. Bucketing is another technique for decomposing data sets into more manageable parts. Bucketing for high cardinality columns:
