Okey, So, Qlik extract the Bit columns as a Boolean format. But, I don't want to make transformations before to ingest the data in the data lake. It is possible?

Hello @pbellonch ,

We might transform the data then load into data lake, or load into data lake straightly without transformation and then convert the data types while consuming the data in data lakes. Both options should be fine.

Do you not want Replicate to do an implied transformation? Or do you not want to add a transformation of your own to the Replicate task?

What do you have in the CSV file? "true"/"False" or true/false ? What do you want? 0/1

Some things to investigate.

  • Some of the Source endpoints have "Map BOOLEAN to Replicate BOOLEAN data type (instead of STRING (5)) option in the Advanced tab". Is that available?  Check that out.

  • Global transformation rules, or per-table, per-column transformation. Change column datatype from BOOLEAN to INT1
