Lock-free state cache #9320
Description
State cache is currently using LinkedHashMap which is not ideal for concurrent access. Each get requires taking a write lock for the cache refresh. This makes parallel requests for a recent state data inefficient.
LinkedHashMap should be replaced with a data structure that is either lock-free or implements copy-on-write semantics. E.g. ARCache
