Scylla is an open-source database alternative to Apache Cassandra, designed to offer higher throughput, low latency, and high availability for real-time applications. Implemented in C++ rather than Java, Scylla provides better control over low-level operations and avoids latency issues associated with garbage collection. Its shared-nothing architecture assigns a single thread per core to enhance performance scalability. Recent integration improvements allow users to monitor Scylla clusters' health, visualize key metrics, and set alerts for performance issues. Scylla maintains fault tolerance using replication factors and consistency levels, and users can track resource utilization and optimize database operations to prevent query timeouts and manage disk space effectively. By leveraging Datadog integration, users can gain comprehensive insights into Scylla's performance alongside other technologies, ensuring efficient operation and resource use.
