Need Help - What happens when number of rows to be refreshed exceeds 10 million rows

Hi,

We are using Impala for data source and working on import mode.

I would like to know the behavior of gateway when dataset has more than 10 million rows that needs to be imported.

1. Will it import only first 10 million rows?

2. If the data set has 12 million rows.... Will it import remaining 2 million rows in the next hr ?

3. Will the refresh fail altogether (no rows will be updated)?

Thanks,

Mannu
