Setting advanced connection properties

In the Advanced tab, you can set the following parameters:

• Max file size (MB): Select or type the maximum size of any CSV file used to transfer data to Amazon Redshift. The default value is 1024.
• Number of threads used to upload a file: Select the number of threads used to upload a single file. The minimum number of threads is 1. The maximum value is 64. The default value is 10.
• ODBC driver: The name of the default ODBC driver you are using to connect to Amazon Redshift. The default value is Amazon Redshift (x64).
• Additional ODBC connection properties: Type any additional ODBC connection properties if required.

• Maximum number of files to copy per batch: If you encounter performance issues, try adjusting this number. The default value is 8.

  Note that increasing the number may not necessarily improve performance and may even degrade it. This is because increasing the number of files also increase the load on the server machine, which may degrade performance (depending on the hardware).

• Use proxy server - Select this option to connect via a proxy server, and then provide the proxy connection settings:

  • Host name: The host name of the proxy server.
  • Port: The port via which to access the proxy server.
  • User name: The user name for the proxy server.
  • Password: The password for the proxy server.

  • Scheme: Select which protocol to use to access the proxy server (HTTP or HTTPS). In order to use HTTPS, you must first install the CA certificate that signed the proxy’s certificate on the Replicate Server machine. Do this as follows:

    • On Windows: Add the CA certificate to the Trusted Root Certification Authorities store of Local Computer
    • On Linux: Add the CA certificate to /etc/pki/tls/certs/ca-bundle.crt

5. To reset the parameter value to its default, click the "Restore default value" icon at the end of the row.

More options

These options are not exposed in the UI as they are only relevant to specific versions or environments. Consequently, do not set these options unless explicitly instructed to do so by Qlik Support or product documentation.

To set an option, simply copy the option into the Add feature name field and click Add. Then set the value or enable the option according to the instructions you received.
