Hi,

 

I have requirement where I have to export the Dataiku process output from redshift to CSV file with header on a SFTP site for a complete automation of the process. Could you please provide a possible way how to achieve this ?

 

Regards,

Hi Ravi, 

You can use the "Export to folder" recipe and specify an already setup connection to your SFTP.

Hi,

Is it possible to append the datetimestamp at the end of the file name using this recipe ?

Also I used the export folder functionality and it failed with following log

Is it possible to append the datetimestamp?
No, we don't have the feature implemented.

For the error, what version of DSS do you use?

A first guess is that the file is too big for the throughput of the connection/SFTP server that closes the connection after a while if the upload takes too much time.

You can try with smaller files first and(or) upload directly from an SFTP client outside of DSS to check the stability of the upstream connection?
Hi,

We are using Dataiku 5.1.5 version and file is only 900 records.

My guess is that issue is because of following command but I am not sure how to correct this one.

Hi,

I am able to put the file on FTP server but I have two issues
a. File Name is same as table name and I want to change it to the new name.
b. Adding the Datatimestamp at the end of the file.

I referred to following link to replicate the process, but somehow file is not being created

https://answers.dataiku.com/1038/export-to-folder-different-name-each-day

Could you please check and suggest something ?
