Hive Determine Number Of Buckets at Brock Clemes blog

Hive Determine Number Of Buckets. Bucketing properties define how the data is. Depends what you are trying to do. Num_buckets is the number of buckets you want to create. And when we want to retrieve that data, hive knows which partition to check and in which bucket. With bucketing, we can tell hive group data in few “buckets”. Bucketing is a very similar concept, with some important differences. Here, we split the data into a fixed number of buckets, according to a hash function over some set of. To decide the number of buckets to be specified, we need to know the data characteristics and the query we want to execute. Hive writes that data in a single file. If you are looking for bucket information on a partition use below command. How to decide the number of buckets? In general, the bucket number is determined by the expression hash_function (bucketing_column) mod num_buckets.
