Bucketing Syntax In Hive at Ronald Kinney blog

Bucketing Syntax In Hive. Bucketing is usually applied to columns that have a very high number of unique values. 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). Bucketing decomposes data into more manageable or equal parts. The range for a bucket is determined by the hash value of one or more columns in the dataset (or hive metastore table). Allows the correct number of reducers and the cluster by column. Bucketing segregates records into a number of files or buckets. Bucketing is a very similar concept, with some important differences. Bucketing is another strategy used for performance improvement in hive. The command set hive.enforce.bucketing = true; Bucketing in hive is the concept of breaking data down into ranges, which are known as buckets, to give extra structure to the data so it may be used for more efficient queries. With partitioning, there is a possibility that you can create multiple small partitions based. Here, we split the data into a fixed number of buckets, according to a hash function over some set of.
