Partition Range Iterator is a concept in Apache Cassandra, a distributed NoSQL database. It refers to a mechanism that is used to read data from a specific range of partitions in a Cassandra cluster.
When a client queries data from Cassandra, it can specify a partition key range to limit the scope of the query. The partition range iterator then retrieves only the data that falls within the specified range, which can improve query performance by reducing the amount of data that needs to be scanned.
The partition range iterator is an important component of the Cassandra query architecture, and it plays a crucial role in ensuring that queries are executed efficiently in a distributed environment.
