ScyllaDB Manager, Repair and Tombstones

ScyllaDB University offers a comprehensive lesson on ScyllaDB Repair and ScyllaDB Manager, focusing on the importance of repairs in maintaining data consistency across nodes and the role of tombstones in data deletion processes. ScyllaDB Repair is a background process that synchronizes data among nodes to ensure all replicas are consistent, addressing common misconceptions about the nature of repairs. The lesson also delves into the functionality of ScyllaDB Manager, a centralized tool for cluster administration and automation of tasks like repairs and backups, highlighting its enhancements in version 2.0, which now utilizes the Manager Agent instead of SSH for node communication. Additionally, the lesson covers practical aspects of backup and restore operations, encouraging learners to engage with a hands-on lab to solidify their understanding and track their progress within ScyllaDB University.
