Can we recommend TDCH for Extract-Load process - forum topic by TDThrottle

Hi,
We all knew TDCH use JDBC connectivity to establish connectivity between Hadoop and Teradata and to move data across these platforms.
My question is using JDBC, if FastLoad operation is interrupted for some reason, it must be restarted from the beginning. This issue is quite frequent when large record set is loaded because Checkpoint feature is not available using JDBC connectivity. Seems even in recent JDBC 15.x release Checkpoint feature is not introduced.
Having this open item, could someone guide me:
1. Can we recommend TDCH (Hadoop-to-Teradata) to move data in regular interval for large IDW system
2. QueryGrid (LOAD_FROM_HCATALOG) - use JDBC connectivity or different mechanism
3. What is the internal latency involved on Teradata while using TDCH/QueryGrid, more specific to AWT usage
Thanks!!
