jasync-sql is an asynchronous, Netty-based database driver for MySQL and PostgreSQL written in Kotlin, usable from Java and Kotlin. It provides non-blocking connection pools and query execution returning CompletableFuture-based results, with an optional R2DBC extension.

Use cases

• connect to MySQL asynchronously from Kotlin
• run non-blocking PostgreSQL queries in Java
• replace blocking JDBC with an async database driver
• use a reactive database driver with R2DBC for MySQL
• manage async database connection pools on the JVM
• execute SQL queries without blocking threads

When to choose

• you need non-blocking database access on the JVM for MySQL or PostgreSQL
• you build reactive or high-concurrency services and want CompletableFuture/R2DBC integration
• you prefer a lightweight Netty-based driver over traditional JDBC drivers

When to avoid

• you need synchronous JDBC semantics or broad JDBC ecosystem compatibility
• you use a database other than MySQL or PostgreSQL
• your stack depends on mature, battle-tested drivers like pgjdbc or Connector/J
