![]() Most outstanding one is PostGIS which brings Geospatial capabilities to Postgres.īesides, there is Foreign Data Wrapper (FDW) to allow querying into other data systems, pg_stat_statements MySQL 8.0 also supports these window functions. Performance: In general, Postgres implementation of window functions is considered more efficient and performant than MySQL implementation.Īdvanced Functions: Postgres supports more advanced window functions, such as LAG(), LEAD(), FIRST_VALUE(), and LAST_VALUE(). Range Units: MySQL only supports the UNBOUNDED PRECEDING and CURRENT ROW range units, while Postgres supports more range units, including UNBOUNDED FOLLOWING, and BETWEEN. Postgres, on the other hand, supports both ROWS and RANGE frame types. Window Frame Types: MySQL only supports the ROWS frame type, which allows you to define a frame consisting of a fixed number of rows. SELECT, UPDATE, and DELETE following a CTE.SELECT, UPDATE, INSERT, DELETE following a CTE.SELECT, UPDATE, INSERT, DELETE inside a CTE.Postgres has a more comprehensive support for CTE: More operators to access JSON features.JSONīoth Postgres and MySQL support JSON column. Postgres also supports logical replication via its Publish/Subscribe mode. Replication is logical replication using binlog. Replicationįor Postgres, the standard replication is physical replication using WAL. Postgres supports the additional Row Level Security (RLS) out of the box, while MySQL needs to createĮxtra views to emulate this behavior. Overall, Postgres provides a stronger transaction support: Database Features Object Hierarchyīoth databases provide ACID transaction. Unless your business reaches Uber-like scale, the sheer database performance is not a deciding factor.Ĭompanies like Instagram, Notion also able to herd The Part of PostgreSQL We Hate the Most.Why Uber Engineering Switched from Postgres to MySQL.Saying that, MySQL does have an edge over Postgres for extreme write-intensive workloads. On the other hand, regardless of which database you choose, if your query misses an index, it could be 10x ~ 1000x degradation. Performanceįor most workloads, the performance between Postgres and MySQL is comparable with at most 30% variations. ![]() ![]() It's recommended to proxy the connection via a connection pooler such as PgBouncer or pgcat. The other hand, the process model consumes more resources. Thus Postgres provides better isolation, e.g.Īn invalid memory access bug only crashes a single process instead of the entire database server. Per connection where each connection spawns a new thread. Postgres uses process per connection where each connection spawns a new process. ![]() Reason that MariaDB is forked from MySQL. Postgres is released under the PostgreSQL license which is a liberal Open Source license similar toĮven though MySQL adopts GPL, some people still are concerned that MySQL is owned by Oracle.MySQL community edition is licensed under GPL.We also use Postgres instead of PostgreSQL throughout the article, though we know the latter is the official name, which is considered as the biggest mistake in Postgres History. Unless otherwise specified, the comparison below is between the latest major release, Postgres 15 vs. Our founders also build Google Cloud SQL, one of the largest hosted MySQL & Postgres cloud services.īased on our operating experience, below we give an extensive comparison between Postgres and MySQL With both databases as well as their derivatives. While Postgres positions itself as the world's most advanced open source relational database.Īt Bytebase, we work with both databases extensively since the Bytebase product needs to integrate Probably still the world's most popular open source database by install base. Over the first place spot from MySQL and become the most admired, desired database.Īs Postgres gains more momentum, it becomes harder to pick between Postgres and MySQL. The 2023 Stack Overflow survey shows that Postgres has taken
