Cassandra Update Partition Key Value at Gordon Rowell blog

Cassandra Update Partition Key Value. 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. You need to specify all keys in a table. A single column primary key is also called a partition key. Like insert, update is an upsert operation: The update statement writes one or more columns for a given row in a table. Update writes one or more column values to a row in a cassandra table. The where`clause is used to select the row to. Each update statement requires a precise set of primary keys to be specified using a where clause. I can alter the first table and add a 'partition' column to the end, and then copy in correct order, but i can't update all the rows in. This token value is compared with the token range for each node to identify the. When cassandra is deciding where in the cluster to store this particular piece of data, it will hash the partition key. On the data write, cassandra uses a hash function to calculate the token value from the partition key.
