How To Define Number Of Buckets In Hive. Few things to keep in mind (based on my own experience): Don't make buckets to small, preferably bigger than the hdp block size. 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. Essentially when you load data you often do not want one load per mapper (especially for partitioned loads because this results in. Basically, this concept is based on hashing function on the bucketed column. Bucketing properties define how the data is organized into buckets within the table. They are specified using the clustered by clause. Along with mod (by the total number of buckets). In general, the bucket number is determined by the expression hash_function (bucketing_column) mod num_buckets. Essentially when you load data you often do not want one load per mapper (especially for partitioned loads because this results in.
