Bucketing Vs Partitioning Hive at Gabriel Cadet blog

Bucketing Vs Partitioning Hive. In conclusion to hive partitioning vs bucketing, we can say that both partition and bucket distributes a subset of the table’s data to a subdirectory. It gives extra structure to the data which can be used for more efficient queries. Partitioning feature is very useful in hive, however, a design that creates too many partitions may optimize some queries, but be detrimental for other important queries. Ideal when partitions are large enough to avoid the small file problem. If, instead, there will be a lot of distinct values which might not be as evenly distributed, consider bucketing instead. In bucketing, the partitions can be subdivided into buckets based on the hash function of a column. Choose columns with a reasonable number of distinct values. While not technically partitioning, bucketing involves dividing data into buckets based on a hash function applied to one or more columns. The major difference is that the number of slices will keep on changing in the case of partitioning as data is modified, but with. Partitioning would be the best choice. Hence, hive organizes tables into.
