## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: database-driver, database, concurrency
- domain: databases, backend, developer-tools
- platform: jvm, cross-platform
- tags: mysql, postgresql, netty, async, reactive, connection-pool, r2dbc, jdbc-url
