Explore a comprehensive database seminar talk on Litestream and its role in revolutionizing single-node deployments. Delve into the fundamentals of SQLite, its layout, and historical significance. Examine the Right Ahead Log, cost of computing, and database performance metrics. Analyze SQL Wall, scans, page pointers, and asynchronous replication techniques. Compare virtual memory with rollback journal and understand the cost model. Gain insights from Livestream's lessons, explore LightFS and Postgres, and learn about Console usage. Investigate database size considerations, additional features, and alternatives like graph-based and VFS-based replication. Conclude with a summary of PostgreSQL applications and participate in a Q&A session to solidify your understanding of modern database deployment strategies.
