Our review
Pros
  • Offers access through either a PoolingDriver or PoolingDataSource
  • Configures pool capacity, validation, wait times and idle eviction
  • Supports abandoned-connection removal and optional prepared-statement pooling
  • Built-in pooling pairs with reactive, non-blocking database access.
  • Supports PostgreSQL, MySQL, MariaDB, DB2, and SQL Server.
  • Offers streaming, TLS/SSL, and database-specific query capabilities.
Cons
  • Requires integration into a Java application rather than offering a hosted service
  • Uses JDBC; it does not provide transaction pooling
  • Documentation describes generic JDBC connections rather than named database support
  • Pooling is embedded in the application, not a separate pooling service.
  • Prepared-query caching is limited to PostgreSQL, MySQL, and DB2.
  • PostgreSQL command pipelining is specific to PostgreSQL.
