Thanks to both of you. Put does not seem to be good enough option.
even at client 2 i look for the counter but cache may have old data. For example two threads in parallel processed same key and counter 2 came first and 1 came later into the cache. client 2 here may skip the update came with counter 1 here but cache now having wrong data of counter 1. yes, i am not interested in acknowledgement. I want to know if putasync uses striped threadpool. i could not find below information in document.
