Cassandra Update Partition Key at Megan Graves blog

Cassandra Update Partition Key. a single column primary key is also called a partition key. while this might be possible with a rdbms and sql, it is not possible with cql in cassandra. use a composite partition key in your primary key to create a set of columns that you can use to distribute. This token value is compared with the token range for each node to identify the node the data belongs to. since cassandra processes an update as an upsert, it is possible to create a new row by updating it in a table. Let’s look at an example. When cassandra is deciding where in the cluster to store this particular piece of data, it. the update statement writes one or more columns for a given row in a table. on the data write, cassandra uses a hash function to calculate the token value from the partition key. Returns one or more rows from a single cassandra table. The where`clause is used to select the row to. retrieve data from a cassandra table.
