Falcon - Dependency

Dependency

Display the dependent instances which are dependent on the given instance. For example for a given process instance it will list all the input feed instances(if any) and the output feed instances(if any).

An example use case of this command is as follows: Suppose you find out that the data in a feed instance was incorrect and you need to figure out which all process instances consumed this feed instance so that you can reprocess them after correcting the feed instance. You can give the feed instance and it will tell you which process instance produced this feed and which all process instances consumed this feed.

NOTE: 1. instanceTime must be a valid instanceTime e.g. instanceTime of a feed should be in it's validity range on applicable clusters, and it should be in the range of instances produced by the producer process(if any)

2. For processes with inputs like latest() which vary with time the results are not guaranteed to be correct.

Usage: $FALCON_HOME/bin/falcon instance -type <<feed/process>> -name <<name>> -dependency -instanceTime "yyyy-MM-dd'T'HH:mm'Z'"

For example: $FALCON_HOME/bin/falcon instance -dependency -type feed -name out -instanceTime 2014-12-15T00:00Z name: producer, type: PROCESS, cluster: local, instanceTime: 2014-12-15T00:00Z, tags: Output name: consumer, type: PROCESS, cluster: local, instanceTime: 2014-12-15T00:03Z, tags: Input name: consumer, type: PROCESS, cluster: local, instanceTime: 2014-12-15T00:04Z, tags: Input name: consumer, type: PROCESS, cluster: local, instanceTime: 2014-12-15T00:02Z, tags: Input name: consumer, type: PROCESS, cluster: local, instanceTime: 2014-12-15T00:05Z, tags: Input
