Retrieval by scanning a partition

Scanning partition when the table has more than one clustering column and comparing groups of clustering keys to certain values.

Queries can scan a partition to retrieve a segment of stored data. The segment must be sequentially stored, so clustering columns can be used to define the slice of data selected.

Procedure

Create a table race_times to hold the race times of various cyclists for various races.

CREATE TABLE cycling.race_times (race_name text, cyclist_name text, race_time text, PRIMARY KEY (race_name, race_time));

Scan the race times in the table to find a particular segment of data using a conditional operator.

SELECT * FROM cycling.race_times WHERE race_name = '17th Santos Tour Down Under' AND race_time >= '19:15:19' AND race_time <= '19:15:39' );
