YugabyteDB is a distributed SQL database that supports snapshot isolation and serializable isolation levels, allowing developers to configure the desired level of concurrency and consistency for their applications. The database also allows users to create read-only accounts with limited permissions, enabling secure access to data without compromising performance. YugabyteDB uses DocDB as its persistence layer and employs the Raft algorithm to ensure data replication across nodes in the cluster. While auto-incrementing IDs can introduce bottlenecks in distributed SQL databases, using UUID columns or serial columns with caching can provide more efficient alternatives. The database also supports various features such as colocated tables, longhorn storage, and integration with Kubernetes. Developers can explore YugabyteDB's capabilities by following tutorials, watching videos, or attending upcoming events.
