How To Use Bucket In Hive at Maxine Smith blog

How To Use Bucket In Hive. learn how to improve query performance in apache hive by implementing data bucketing. working of bucketing in hive. The concept of bucketing is based on the hashing technique. in apache hive, for decomposing table data sets into more manageable parts, it uses hive bucketing concept. Here, modules of current column value and the number of required buckets is calculated (let say, f (x) % 3). In hive, we have to enable buckets by using the set.hive.enforce.bucketing=true; to query records from a particular bucket, the syntax below can be used. bucketing in hive is useful when dealing with large datasets that may need to be segregated into clusters for. Select col_name from table_name tablesample(bucket x. hive buckets provide a way to group data into more manageable chunks for faster querying and processing. Now, based on the resulted value, the data is stored into the corresponding bucket. buckets use some form of hashing algorithm at back end to read each record and place it into buckets; Step 1) creating bucket as shown below.
