_open and _close index not supported in AWS service

[CosX]

This is an issue experienced with the implementation of synonyms. Today the list of synonyms closes an index, loads settings including synonym list and reopens index.

Comments on https://stackoverflow.com/a/33923322/1702945 suggests creating an alias and rebuilding index on changed settings.

There are plans to use the alias approach in other areas, to avoid downtime when doing changes in the settings. Unfortunately there is no ETA on this yet.

A pre-release supporting synonyms_path exists, but that might not help in your scenario?

Does the pre-release of synonyms_path avoid using the _close endpoint?

Yes, this is just a flat file in the config-folder. It doesn't touch the settings. The downside is that it is harder to maintain, espesially from an editors perspective.
