java - Multiple theads access Memcache -

what happen if multiple thread access same object stored in memcached ??

i have object objstore stored in memcached.

each thread retrieve objstore memcached , change , again store memcached.

at same time in module if want fetch same object objstore memcached, return empty object.

i using memcache 1.4 version.

memcached hold last version of object. if get, modify , put have no guarantee put applies same value get. use cas operations (gets, cas) if need synchronize.
