| ---+++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 |
