#Feeder Service
Monitors a directory for new files, file thresholds may be set to the number of files, size in bytes, or age of files. Files will be moved to a target directory and posted to a message topic.

One service per directory to be monitored. Each directory will have a single associated dataType and InputFormatClass


##FileScannerProperties (prefix: file)
`file.inputDir` - Directory to monitor for new files

`file.frequency` - time in MS to scan file.inputDir for files to process

`file.ignorePrefix` - Files that match this prefix will not be processed

`file.maxAge` - (default -1) max age in MS before a file should be processed regardless of count or size

`file.maxSize` - (default -1) max size in bytes an aggregated set of files should be before they should be processed regardless of count or age

`file.maxFiles` - (default -1) max number of files before files should be processed regardless of age or size

`file.recursive` - (default false) if true recursively search inputDir for files

`file.errorRetryInterval` - (default 60000) interval that a file should not be retried if it resulted in a processing error

`file.errorRetryTimeUnit` - (default MILLISECONDS) default time unit for errorRetryInterval

`file.fsConfigResources` - List of files to be added to Configuration, applied in order. This should include hadoop core/site 

##FeederProperties (prefix: feeder)
`feeder.targetDir` - location to move files once they have been fed

`feeder.inputFormatClass` - expected class of files the feeder is monitoring in file.inputDir

`feeder.dataType` - expected dataType of files the feeder is monitoring in file.inputDir

`feeder.preservePath` - if true, any part of the path beyond the file.inputDir will be preserved when moving the file to feeder.targetDir

##Additional Configuration (Spring Boot)
`spring.cloud.stream.bindings.feedSource-out-0.destination` - target exchange for messages

###Environment:
`DEST_QUEUE` - environment variable, defaults to ingest. May override to direct feeder messages to another queue
