The table below describes the settings in the Advanced tab.
Setting
Description
File Format
Expand this section to specify or view the file format settings.
Target storage format
Select either Text or Sequence.
Information note
When using Text as the target storage format, new lines as part of the data values are not supported (due to an Apache Hadoop limitation). Best practice is to use Sequence as the target storage format.
Field delimiter
The delimiter that will be used to separate fields in the target file. The default is \001. Note that field delimiters should be ASCII characters unless they are non-printable control characters, in which case they should be in Octal format (e.g. \247).
Null value
The value that will be used to indicate a null value in the target file.
Example (where @ is the null value):
mike,male,295678
sara,female,@
Escape character
The escape character is used to escape the field delimiter character. When a field delimiter is escaped, it is interpreted as actual data, and not as a field delimiter.
Example (where \ is the escape character and a comma is the field delimiter):
sunroof\,power-steering
Add metadata header
You can optionally add a header row to the data files. The header row can contain the source column names and/or the intermediate (i.e. Replicate) data types.
Example of a target file with a header row when both With column names and With data types are selected:
Position:DECIMAL(38,0),Color:VARCHAR(10)
1,"BLUE"
2,"BROWN"
3,"RED"
...
File Attributes
Expand this section to specify or view the file attributes.
Maximum file size
Specify the maximum file size of each target file. When the data reaches the maximum size, the file will be closed and written to the specified target folder.
Compress files using
Select the compression method to use on Google Cloud Storage.
Change Processing
Expand this section to specify or view change processing settings.
Apply/Store changes when:
File size reaches
Specify the minimum size of the data required to create a file in idle state.
Elapsed time reaches
Specify the maximum time to wait before applying the changes in idle state.
Information note
To facilitate rapid delivery of DDL messages, files are uploaded immediately, regardless of the specified File size reaches or Elapsed time reaches values.
Proxy Server
Expand this section to specify or view proxy settings.
Use proxy server
Select this option to access Google Dataproc via a proxy server.
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 accessing the proxy server.
Password
The password for accessing the proxy server.
Scheme
Select which protocol to use to access the server (HTTP or HTTPS).
Information note
The proxy configuration applies to the Google Cloud Storage, but not to the ODBC connection.
Internal parameters
Internal parameters are parameters that are not exposed in the UI. You should only use them if instructed by Qlik Support.
To add internal Qlik Replicate parameters:
Click the Internal Parameters link.
The Internal Parameters dialog box opens.
In the edit box, type the name of the parameter you need to add and then click it.
The parameter is added to the table below the search box with its default value.
Change the default value as required.
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.
Settings summary
You can view a summary of your settings by clicking the Setting Summary link. This is useful if you need to send a summary of your settings to Qlik Support.
