The Continuent Tungsten configuration includes a number of filter configurations by default. However, not all filters are given a default configuration, and for some filters, multiple configurations may be needed to achieve more complex filtering requirements. Internally, filter configuration is defined through a property file that defines the filter name and corresponding parameters.
For example, the
configuration is defined as follows:
The first line creates a new filter configuration using the corresponding
Java class. In this case, the filter is named
rename, as defined by the string
Configuration parameters for the filter are defined as values after the
filter name. In this example,
definitionsFile is the name of
the property examined by the class to set the CSV file where the rename
definitions are located.
To create an entirely new filter based on an existing filter class, a new property should created with the new filter definition in the configuration file.
Additional properties from this base should then be used. For example, to
create a second rename filter definition called
The filter can be enabled against the desired stage using the filter name
