Creating a partition on state splits the table into around 50 partitions, when searching for a zipcode with in a state (state=’CA’ and zipCode =’92704′) results in faster as it need to scan only in a state=CA partition directory.

Hive Partition is a way to organize large tables into smaller logical tables based on values of columns; one logical table (partition) for each distinct value. Each bucket is stored as a file within the table’s directory or the partitions directories. Our visitors often compare Hive and Spark SQL with Impala, Snowflake and Amazon Redshift.

Some form of processing data in XML format, e.g. We invite representatives of system vendors to contact us for updating and extending the system information,and for displaying vendor-provided information such as key customers, competitive advantages and market metrics. Since Bucketing works on hashing, if the data is not equally distributed between hashes, it results in in-equal files and may get into performance issues.

Apache Spark and Apache Hive are essential tools for big data and analytics. You can have one or more Partition columns, You can’t manage the number of partitions to create, You can manage the number of buckets to create by specifying the count, Bucketing can be created on a partitioned table. Hive Bucketing a.k.a (Clustering) is a technique to split the data into more manageable files, (By specifying the number of buckets to create). When creating partitions you have to be very cautious with the number of partitions it creates, as having too many partitions creates too many sub-directories in a table directory which bring unnecessarily and overhead to NameNode since it must keep all metadata for the file system in memory.
