Is there a list of allowed IP addresses for Transfer?

22.214.171.124/32 126.96.36.199/28 188.8.131.52/32 184.108.40.206/28 220.127.116.11/32 18.104.22.168/28 22.214.171.124/32 126.96.36.199/28 188.8.131.52/32 184.108.40.206/28 220.127.116.11/32 18.104.22.168/28 22.214.171.124/32 126.96.36.199/28 188.8.131.52/32 184.108.40.206/28 220.127.116.11/32 18.104.22.168/28 22.214.171.124/32 126.96.36.199/28 188.8.131.52/32 184.108.40.206/28 220.127.116.11/32 18.104.22.168/28
Why is my transfer taking this long to start?
Each transfer takes its own compute instance to execute. On launch, before the transfer can start, the most time-consuming stage is allocating the necessary resources for this instance.
Depending on a connector type, Transfer may extract a schema which may also take some time.
Does Transfer support encryption?
If a DoubleCloud cluster (source or target) has encryption enabled, Transfer will support this encryption.
Can I transfer empty tables in Transfer?
Transfer doesn't support transfer of empty tables or other empty entities.
There's an exception. In homogeneous transfers, you can copy metadata separately. In this case, empty tables and other entities (views, triggers etc.) will be transferred.
