Introduction to the interface of storm transaction topology

• itransactionalspout Basic transaction Topology spout interface, contains two parts interface: coordination spout interface and message sending blot interface.

• Transactionalspoutbatchexecutor Bolt type, used to execute the message sending Bolt node in Itransactionalspout.

• Transactionalspoutcoordinator The spout type, used to perform the coordination spout node in the Itransactionalspout, is the only spout node in the system, with the function of initializing the transaction and generating the transaction attempt message.

• The spout interface of the transaction topology of the ipartitionedtransactionalspout partition, through which the user accomplishes the spout partitioning function.

• The partitionedtransactionalspoutexecutor is a itransactionalspout type and is mainly used to fit the Ipartitionedtransactionalspout interface, Actuators for the ipartitionedtransactionalspout.

• The spout interface of the iopaquepartitionedtransactionalspout partition's fuzzy transaction topology, through which the user accomplishes the topology of the fuzzy transaction type.

• Opaquepartitionedtransactionalspoutexecutor is a icommittertransactionalspout type, For the Iopaquepartitionedtransactionalspout interface, the actuator for the iopaquepartitionedtransactionalspout.

• icommittertransactionalspout The spout interface of a transactional topology that has a commit function, primarily for the spout node of a fuzzy transaction topology.
