In this module, learn the pivotal role of the controller in managing the cluster, including node failure recovery, segment replication, and assignment. Discover how the controller, functioning as an Apache Helix controller, maintains global metadata and interfaces with ZooKeeper for durable state storage. Additionally, learn about Pinot’s native support for multitenancy through hardware isolation and tenant tagging, ensuring data segregation for optimized performance.
