- In this example the columns that comprise of the table row are specified in a similar way as the definition of types. Comments can be attached both at the column level as well as at the table level. Additionally the partitioned by clause defines the partitioning columns which are different from the data columns and are actually not stored with the data. The bucketed on clause specifies which column to use for bucketing as well as how many buckets to create. The delimited row format specifies how the rows are stored in the hive table. In the case of the delimited format, this specifies how the fields are terminated, how the items within collections (arrays or maps) are terminated and how the map keys are terminated. STORED AS SEQUENCEFILE indicates that this data is stored in a binary format (using hadoop SequenceFiles) on hdfs. The values shown for the ROW FORMAT and STORED AS clauses in the above example represent the system defaults.

  == Sampling ==
- The sampling clause allows the users to write queries for samples of the data instead of the whole table. Currently the sampling is done on the columns that are specified in the BUCKETED ON clause of the CREATE TABLE statement. In the following example we choose 3rd bucket out of the 32 buckets of the pv_gender_sum table:
