====== Data Core: Create an Event Subscription ======

Event Sources push events to subscribed Event Sinks. 

Event Sinks subscribe to Event Sources to process events. For example, save event to a log or database, send an email, etc…

The example below shows a subscription between a SQL Event Source (which collects data from SQL Server) and Big Data Event Sink (which stores data to Elasticsearch).

For a full collection of Data Core components and configuration, see [[data_core:data_sources| Data Core Components]]
