MySQL
An open-source relational database management system that can be integrated with Dify to support data reading and writing in AI applications.
Core Facts
Debezium is one of the most well-known CDC platforms, supporting real-time streaming of database changes to message queues such as Kafka
In Docker's network model, containers cannot directly use localhost to access the host machine's MySQL by default; typically the host's actual LAN IP or the special domain name host.docker.internal in Docker Desktop for Windows is needed to point to the host machine.
Dify deployed via Docker can communicate with MySQL 8 on a Windows host machine and also with databases in a VMware virtual machine.
Timeline (last 90 days)
Seqora is a desktop database client that supports PostgreSQL, MySQL, MariaDB, and SQLite.
MySQL offers EXPLAIN FORMAT=JSON and EXPLAIN ANALYZE.
PostgreSQL provides the pg_stat_user_indexes view to count index scans, and MySQL's performance_schema records index usage statistics.
PostgreSQL's interactive shell is called psql, and its special commands begin with a backslash (such as \dt to list tables); MySQL's shell is called mysql and uses SQL-like commands such as show tables and describe.
SQLite uses || for string concatenation, whereas MySQL uses the CONCAT() function.
Historically, the maturation of open-source databases such as MySQL and PostgreSQL forced commercial databases to shift from per-seat licensing to usage-based or subscription pricing.
Dify supports deployment on Windows systems via Docker.
This test targeted only the Oracle dialect, and the two rules were distilled from manual analysis of failure cases; for other dialects such as MySQL and PostgreSQL, whether similar high-frequency error patterns exist requires separate attribution analysis.
The project database uses MySQL as an example, but any database such as the domestic Dameng, MySQL, or PostgreSQL can be chosen.
In MySQL, a read-only session can be achieved through SET SESSION TRANSACTION READ ONLY or a read-only account.
