PGConf NYC 2021 Flexible Indexing with Postgres by Bruce Momjian

Flexible Indexing with Postgres by Bruce Momjian When considering database indexing, many people are confused by the many Postgres indexing structures available, and the many datatypespecific index lookup methods. For example, brin allows for efficient indexing of many columns. gin indexing specializes in the rapid lookup of keys with many duplicates an area where traditional btree indexes perform poorly. This is particularly useful for json and full text searching. GiST allows for efficient indexing of twodimensional values and range types. This talk explores the various indexing features of Postgres and when to use them. This is ideal when presented after my NonRelational Postgres presentation.
