Introduction to Event Adapters

All external datasources and data sinks use event adapters as the entry and exit points for processing data streams. Event adapters facilitate maintaining connections to datasources and data sinks from the WSO2 product servers. Event adapters are of two types as follows:

• Input event adapters: used to receive events from an event source
• Output event adapters: used to publish events to an event sink

By default, WSO2 products support the following input event adapters and output event adapters. Also users can write custom event adapters.
