public class ReadConnectionPool extends ConnectionPool
Purpose: The read connection pool is used for read access through the server session. Any of the connection pools can be used for the read pool however this is the default. This pool allows for concurrent reads against the same JDBC connection and requires that the JDBC connection support concurrent read access.
