App local files updated in indexer cluster

[FritzWittwer]

I have an app which included a custom command which in turn has to cache some information on the indexer it runs. What is the best location to store this file, is $SPLUNK_HOME/etc/apps/<appname>/lookups/<my_cache_file_name>.cache sensible?
What will the indexer cluster do with this files?

Just in case you wonder, the caches are to large to distribute them with the replication bundle as a lookup table.  They are filled by reading the kvstore from the calling search head with REST calls.

As you should install this by CM then the correct place will be SPLUNK_HOME/etc/slave-apps/... instead of apps.
