Strengths and trade-offs
Tomcat JDBC Connection Pool — where it wins
- Configurable active and idle connection counts, validation and recovery settings
- Asynchronous connection retrieval returns a Future
- JMX monitoring, XA support and pluggable JDBC interceptors
Where it doesn't
- Uses JDBC drivers rather than providing database connectivity itself
- Deployment is self-hosted, as a Tomcat resource or standalone data source
- Pools JDBC connections rather than providing separate transaction pooling
Microsoft.Data.SqlClient — where it wins
- Connection pooling is enabled by default, with configurable pool sizes.
- Supports async connection opening, command execution, and transactions.
- Offers Entra ID authentication options and strict TLS encryption.
Where it doesn't
- Supports SQL Server and Azure SQL only.
- Pooling is client-side and embedded, not a standalone pooling service.
- Does not provide transaction pooling.
