Abstract
A computer-implemented method for transferring changes made to data from a data source to a data destination may be provided. The method involves using a message broker with streaming channels for transferring data changes from a data source to a data consumer. To determine if data has changed, a portion of data labeled with a key is sent through a hash function. A hash value with the corresponding key that has already been sent to the data consumer is retrieved from a streaming channel and compared to the newly created hash value. If the newly created hash value is different the data is sent to data consumers by the message broker via one streaming channel, while the new hash value is stored in the other streaming channel.
