There's AWS Glue and Azure Data Factory, integration tools like Qlik Replicate or FiveTran Replication, or ConnX solutions if you have enterprise-scale money to burn.

We don't use any of them though, we have custom C# ingestion code that can talk to most databases and Odata API's. .Net's lazy collections make it quite easy to create a consumer/producer pipeline for streaming large datasets without too much overhead.
