Package org.hibernate.reactive.pool.impl

Class SqlClientPool

  • All Implemented Interfaces:
    java.io.Serializable, ReactiveConnectionPool, org.hibernate.service.Service
    Direct Known Subclasses:
    DefaultSqlClientPool, ExternalSqlClientPool
    public abstract class SqlClientPool
extends java.lang.Object
implements ReactiveConnectionPool
    A pool of reactive connections backed by a supplier of Vert.x Pool instances.

    The Vert.x notion of pool is not to be confused with the traditional JDBC notion of a connection pool: there is a fundamental difference as the Vert.x pool should not be shared across threads or with other Vert.x contexts.

    Therefore, the reactive SessionFactory doesn't retain a single instance of Pool, but rather has a supplier which produces a new Pool within each context.
