** Title : A detailed understanding of MVCC, Transaction ID Wraparound and Autovacuum internals in PostgreSQL. **
*Abstract : *
- PostgreSQL implements MVCC in a slightly different way when compared to databases like Oracle, MySQL and others. In PostgreSQL, you see a different method for managing UNDO which requires a cleanup concept called vacuum. Over a period of time, PostgreSQL implemented autovacuum that has been enhanced with every release. It is now important for PostgreSQL admins/DevOPS to understand the internals of autovacuum and the MVCC implementation. We shall discuss these topics in detail during this talk.
*This talk includes - *
- 1. MVCC in PostgreSQL.
- 2. Transaction ID Wraparound
- 3. Vacuum and Autovacuum Internals.
- 4. Parameters you should know to understand how autovacuum works.
- 5. Problems you may see in a busy OLTP database with untuned autovacuum settings.
- 6. Methods to tune the autovacuum parameters in PostgreSQL.
