Does "db.t4g.medium" support query results cache in Neptune ?

Question

I am trying to enable caching for Neptune, however I have found out that "t2.medium" and "t3.medium" instances are not supported as mentioned here : https://docs.aws.amazon.com/neptune/latest/userguide/gremlin-results-cache.html .

I am currently using "db.t3.medium", if I create a "db.t4g.medium" read replica would that support caching ?

That page should state that the results cache is not available in the t3.medium or t4g.medium instances.  The t-class instances are very constrained in terms of memory and when you enable the results cache feature we "borrow" memory that was originally allocated for query execution.  Thanks for the catch and we'll get the docs updated accordingly.
