Romain Gauthier updated UNOMI-817:
----------------------------------
Description:
For past event conditions, we add a property \{{eventTriggered+md5}} to the
profile and session indexes.
But these properties are never cleaned even if the th condition doesn't exist
anymore.
This can result in a large number of properties getting added to the index, and
could lead to a mapping explosion.
Tech notes:
* These properties need to be moved to a nested property
* pastEventQueryBuilder, pastEventConditionEvaluator, setEventOccurenceCount
action need to be updated
* If there is a way to prevent these properties to be copied to the session,
that would be great
* Requires a migration script, including a full reindexation of the profiles
to clean previous mappings
> past event conditions can generate mapping explosions
