Distinct Partition Key Cassandra at Ricardo Watkins blog

Distinct Partition Key Cassandra. Select statement now allows listing the partition keys. This is a simple showcase on how to select all the distinct partition keys from a cassandra table. The select statement supports functions that perform. So, one way to get this to work, would be to build a specific table to support that query: In this article, we learned that cassandra uses a partition key or a composite partition key to determine the placement of the data in a cluster. Cql 3.1.1 and onwards support distinct operation only for partition keys. Data partitioning is usually performed using a simple mathematical function such as identity, hashing, etc. The function uses a configured data attribute called ‘partition key’ to group. Use the distinct keyword to return only distinct (different) values of partition keys. All of these keys also uniquely identify the data. There is also a corresponding blog post for this project. The way to select a page of distinct partition keys is. The clustering key provides the sort order of the data stored within a partition. Cql has a construct that intrinsically removes duplicate partition key entries from a result set, using the distinct keyword. Distinct only works on partition keys.
