I'm finding increasing use cases to integrate data to the DW / Data lake from the front end of a web / mobile app. In addition to the back end data.
Obviously this can be done with with events wired up in the store/model. I think this type of data suits dumping into a data lake.
However, one key requirement that gets repeated is the analyst want to track the ID from the front end and map it back to the back end (OLTP source). Example use case is to relate user interaction with the app back to the transactions they make.
I do think that front end data is best streamed out as JSON objects asynchronously as the data isn't always relational in the front end and we don't want to create any app blocks.
Has anyone else experienced this use case?
