Hello,
In our application, we have the following scenario. When the user triggers a button(Eg. Copy), we will copy existing data into new by changing a specific key.
For eg:
Existing data (Actual data is in millions):
A1 B1 X0 100
A2 B1 X0 50
A3 B2 X0 75
When the user triggers Eg.Copy to X1. The data will be copied and generated like below:
A1 B1 X0 100
A2 B1 X0 50
A3 B2 X0 75
A1 B1 X1 100
A2 B1 X1 50
A3 B2 X1 75
We use Insert for this case. For more volume (Eg. Millions of rows) the performance is heavily impacted (it runs for >5mins).
Is there any optimization can be applied for such scenario? Like rowstore(we have not tested yet) or delta merge off etc.?
Regards,
Chathia.
