We switched to Fivetran in order to stop maintaining our own ad-hoc connectors, which was brittle and time consuming. Fivetran definitely helps with hiding the complexities of connectors, retries, mapping of fields, etc. It makes it painless to add new connectors, too. Review collected by and hosted on G2.com.
For a product aimed at reducing complexity, we still experience regular problems (once or twice a month) with connectors requiring manual intervention. Also, observability is not straightforward: there used to be a log which could be accessed from the UI, which was then moved to a destination that can be queried with SQL; while the latter is more flexible, for quick checking of problems the UI-accessible log was better. Furthermore, the destination-as-log can be impacted by outages, resulting in situations where you are blind to what the actual problem was. Review collected by and hosted on G2.com.
