The name of the connection service property

The name of the connection string property. For details, see Ndb_cluster_connection constructor

The name of the database property. For details, see the catalogName parameter in the Ndb constructor. Ndb constructor

The name of the maximum number of transactions property. For details, see Ndb::init()

The name of the connection pool node ids property. There is no default. This is the list of node ids to force the connections to be assigned to specific node ids. If this property is specified and connection pool size is not the default, the number of node ids of the list must match the connection pool size, or the number of node ids must be 1 and node ids will be assigned to connections starting with the specified node id.

The receive thread activation threshold for all connections in the connection pool. The default is no activation threshold.

The cpu binding of the receive threads for the connections in the connection pool. The default is no cpu binding for receive threads. If this property is specified, the number of cpu ids in the list must be equal to : a) the connection pool size if the connection pooling is not disabled (i.e. connection pool size > 0) (or) b) 1 if the connection pooling is disabled.

The name of the connection pool size property. This is the number of connections to create in the connection pool. The default is 1 (all sessions share the same connection; all requests for a SessionFactory with the same connect string and database will share a single SessionFactory). A setting of 0 disables pooling; each request for a SessionFactory will receive its own unique SessionFactory.

The number of seconds to wait for all sessions to be closed when reconnecting a SessionFactory due to network failures. The default, 0, indicates that the automatic reconnection to the cluster due to network failures is disabled. Reconnection can be enabled by using the method SessionFactory.reconnect(int timeout) and specifying a new timeout value.

The flag for deferred inserts, deletes, and updates

The name of the jdbc driver

The jdbc password

The jdbc url

The jdbc username

The name of the session factory service interface

The name of the files with names of implementation classes for session factory service
