Description: Nodetool cleanup is a fundamental command in Apache Cassandra, designed to optimize the performance and efficiency of nodes in a distributed database cluster. This command is specifically used to remove unnecessary data after changes in the cluster topology, such as the addition or removal of nodes. When a node is retired or added, there may be orphaned data or data that is no longer relevant, which can lead to inefficient use of storage space and degraded performance. By executing the Nodetool cleanup, it ensures that the node retains only pertinent data, contributing to better resource management and increased speed in read and write operations. This process is crucial for maintaining the integrity and efficiency of the system, especially in environments where scalability and availability are essential. Nodetool cleanup not only helps free up space but also improves data consistency across the cluster, ensuring that nodes operate optimally and that end-users experience smooth and reliable performance.
