When To Use Partition And Bucketing In Hive. 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. Partitioning is used to obtain performance while querying the data. Hive partitioning separates data into smaller chunks based on a particular column, enhancing query efficiency and data. Partitioning in hive is conceptually very simple: For example, in the above table, if we write the below sql, it need to scan all the records in the table which. By understanding the concepts and strategies surrounding partitioning, such as when to use it, what type of partitioning to use (static or. Partitioning the data gives us performance benefits and also helps us in organizing the data. Now, let’s see when to use the partitioning in the hive. Hive bucketing is a way to split the table into a managed number of clusters with or without partitions. Using partition we can make it faster to do queries on slices of the data. We define one or more columns to partition the data on, and then for each unique combination of values in those columns, hive. Comparison between hive partitioning vs bucketing
