scalikejdbc/scalikejdbc-async

This system is a Scala library providing asynchronous database access for PostgreSQL and MySQL, built on top of ScalikeJDBC and the jasync-sql driver. It enables non-blocking SQL operations, including one-to-one and one-to-many relational queries, with configurable connection pooling and SSL support. The library currently supports Scala 2.12, 2.13, and 3, and is in a beta stage of development.

The \scalikejdbc.async\ package has removed several core classes and traits that previously handled asynchronous database operations, including \AsyncDBSession\, \AsyncResultSet\, \AsyncSQLs\, \AsyncTx\, and the internal \Mauricio\ connection implementations. This removal eliminates the legacy async execution paths (such as \single\, \traversable\, and \list\ methods on sessions) and the implicit conversions that enabled them, meaning users can no longer execute asynchronous SQL statements or manage transactions using these specific legacy APIs.

The asynchronous database module has been rewritten to use the jasync-sql driver instead of the previous implementation. This change introduces new configuration options for connection pools (such as max pool size, queue size, and timeouts) via \AsyncConnectionPoolSettings\, adds support for SSL and charset configuration, and provides async wrappers for SQL operations including one-to-one and one-to-many relational queries. Users benefit from improved connection management, better performance through non-blocking I/O, and enhanced compatibility with MySQL and PostgreSQL databases.

The project's build configuration has been upgraded from sbt 0.12.4 to sbt 2.0.9, requiring users to ensure their local environment supports this version. The legacy \sbt-scalariform\ plugin has been removed and replaced with \sbt-scalafmt\ (version 2.6.2) for code formatting, and the \sbt-pgp\ plugin has been updated to version 2.3.2. Additionally, a new \CodeGenerator.scala\ script has been introduced to automatically generate boilerplate code for asynchronous one-to-many SQL operations, streamlining the development of complex query mappings.

project · high confidence

The library has migrated its underlying database driver from the deprecated postgresql-async/mysql-async stack to jasync-sql, requiring users to update their dependencies to use jasync-postgresql or jasync-mysql. This change accompanies a major version bump to 0.19 and updates the project to use Scala 3 dialects in its formatting configuration, while also clarifying that the library is currently in a beta stage.

Deleted the \src/test/scala/example\ test suite, including \Company.scala\, \ExampleDBInitializer.scala\, \MySQLExample.scala\, and \PostgreSQLExample.scala\. These files contained integration tests for database initialization and async query execution (single value retrieval, traversable/list results, and transactional updates) against MySQL and PostgreSQL databases using ScalikeJDBC.

src/test · high confidence

The build definition has been updated to version 0.20.1-SNAPSHOT, adding Scala 3.3.8 to the supported cross-compilation versions alongside 2.12.21 and 2.13.18. Key library dependencies have been upgraded, including scalikejdbc to 4.3.5, jasync-sql to 2.2.4, the PostgreSQL JDBC driver to 42.7.13, and the MySQL connector to 26.7.0. Test dependencies were also updated, setting testcontainers to 2.0.5 and scalatest to 3.2.20, while build settings now include conditional logback-classic inclusion for Java 11+ and specific compiler flags for Scala 3.3+.
