Package org.hibernate.reactive.pool

Class BatchingConnection

  • All Implemented Interfaces:
    ReactiveConnection
    public class BatchingConnection
extends java.lang.Object
implements ReactiveConnection
    A ReactiveConnection that automatically performs batching of insert, update, and delete statements, relieving the client persister code of the responsibility to manage batching. Actual SQL statements are delegated to a given ReactiveConnection which only supports explicit batching using update(String, List).

    Note that in Hibernate core, the responsibilities of this class are handled by JdbcCoordinator and the Batch interface. However, the model used there is not easily adaptable to the reactive paradigm.

        Description copied from interface: ReactiveConnection
        This method is intended to be used only for queries returning a ResultSet that must be executed outside of any "current" transaction (i.e with autocommit=true).

        For example, it would be appropriate to use this method when performing queries on information_schema or system tables in order to obtain metadata information about catalogs, schemas, tables, etc.

        Specified by:
        selectJdbcOutsideTransaction in interface ReactiveConnection
        Parameters:
        sql - - the query to execute outside of a transaction
        paramValues - - a non-null array of parameter values
        Returns:
        the CompletionStage from executing the query.
