This talk discusses the implementation of MVCC as used by PostgreSQL. It describes the need for and role of MVCC, how PostgreSQL accomplishes the same, and what this implementation means for the db engine. We will discuss transactions, readers vs writers, locking, bloat, and autovacuum. You should be familiar with both SQL and PostgreSQL, but the talk aims to be accessible to beginners.
