Actors in LCP are all children of user-guardian and don't have a hierarchy. The idea is to implement a hierarchy. The following hierarchy is not exact but just a illustration - will modify this wiki along with the dev.
LCP Top Level Supervisor Actor:
|
|- Loader
|- Watcher
|- Parser_1_Top_NS
|- Parser_1_Top_NS_Child_NS
|- Parser_1_Top_NS_REF_NS
|- Parser_1_Top_NS_Table
|- LogVault
|- C*
|- Solr
|- R&A
### LCP Development Usecases
1. Configure Akka to send death watch messages to LCP Supervisor Actor
2. One example scenario: LCP Supervisor, which is the guardian of all its actors, will receive a Terminated message when a actor in Parse dies. The action to be taken on this is to terminate all the other actors in that parser (terminate without those actors processing all messages in inbox, idea is to use Akka AllForOneStrategy in all places where there is tight coupling of parent-child). LCP would throw and ERROR that parser-instance 'X' was terminated. Mark that log file as failed with reason as exception message. Recreate a new parser instance to keep the count of active parsers per
configuration setting
3. In case of all routees failing due to write exceptions while writing to Cassandra/Solr/S3 due to Cluster-being-down or network-down etc scenarios, shutdown LCP with a clear ERROR about the failing subsystem
4. To satisfy all the above usecases, more supervisor actors may be needed within LCP
