Is the property "hibernate.search.default.write_metadata_async" established in

HSEARCH-1728 actually still needed, if it can be set automatically depending on whether the backend is async or not? In other words, is there a need to set it to false for an async backend / set it to true for a sync backend? Otherwise it'd be nice to get rid of one of these knobs people need to reason about.

no idea. this is more Sanne Grinovero's cup of tea

If the property still is needed, why is it not named "hibernate.search.

Unknown macro: {default|<index_name}

.infinispan.write_metadata_async"? The property only makes sense for ISPN, and IMO that should be reflected in the name. That was suggested already back then, but apparently that proposal was never picked up.

+1 for the question and property naming. I don't know the answer.
