When adding aliases that include filters to data streams we validate the filter for every index in the data stream. This entails instantiating a temporary index service for every index (at least for every index not on the master node) which in turn means parsing each index's mapping and setting up a mapper instance.
This can take many seconds for larger data streams. It seems we could avoid validating the filter for every index here and just validate for every unique mapping only?
