@Deprecated public class TemplateTap extends BaseTemplateTap<java.util.Properties,java.io.OutputStream>
Tuple
instance.
The constructor takes a FileTap
Tap
and a Formatter
format syntax String. This allows
Tuple values at given positions to be used as directory names.
openTapsThreshold
limits the number of open files to be output to. This value defaults to 300 files.
Each time the threshold is exceeded, 10% of the least recently used open files will be closed.
TemplateTap will populate a given pathTemplate
without regard to case of the values being used. Thus
the resulting paths 2012/June/
and 2012/june/
will likely result in two open files into the same
location. Forcing the case to be consistent with an upstream Function
is recommended, see
