The standard prefix for the datasource is file:// which can be omitted if configured as the default datasource.
This datasource allows to read files and treat the contents as a source of data.
file:///C:/Users/carcassi/mydata.csv will open the file located at C:\Users\carcassi\mydata.csvfile:///home/foo/mydata.csv will open the file located at /home/foo/mydata.csvIt currently does not detect when the file content changes, and there is no way to "refresh" except connecting and disconnecting.
The only supported format is CSV and the data is read as a table. The first line represents the column names and the subsequent lines represents rows of the table. Each element is separated by a space. Strings must be quoted with a double quote.
