Connection Pooling & Transactions
Manage database connections efficiently with pooling and ensure data integrity using transactions in next.jdbc.
Why Connection Pooling?
Opening a new database connection for every query is slow and resource-heavy. A connection pool keeps a set of reusable connections ready, dramatically improving throughput.
The HikariCP Pool
The most popular JVM connection pool is HikariCP. The next.jdbc.connection namespace provides a helper to build a pooled datasource.
