push.replication.ignore.index-redirects (collection.cfg setting)
Specifies if push collections running as query processors (aka slaves) should download the redirect data placed on indexes. This redirect data is used to resolve redirects on the index outside of query processing. When set 'true' push query processors will not be able to resolve redirects outside of the query processor such as on tuning.
Defaults is to include the redirect data.
To save bandwidth you may choose to ignore the redirect files.
