looking for NOSQL distributed database with notify system

Question

I am looking for a NOSQL distributed database that has the ability to notify after data changed (as such as call a web service)

Answer 1

This feature is called change data capture or change streams in most databases. The idea here is that the database offers a way for you to subscribe (or capture) the changes done to the data using some mechanism.

You can search for change data capture <database name> for more details. For example, I was able to find the following links using the appropriate search terms:

• Cassandra: http://cassandra.apache.org/doc/latest/operating/cdc.html
• MongoDB: https://docs.mongodb.com/manual/changeStreams/
• DynamoDB: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html
