[ https://issues.jboss.org/browse/ISPN-5298?page=com.atlassian.jira.plugin.... ] Ion Savin commented on ISPN-5298: --------------------------------- If I understand correctly how expiration is supposed to work we should always be able to satisfy this condition (sync put) regardless of how small the duration/unit is: put(k, v, lifespan, unit) sleep(lifespan, unit) assert(null, get(k)) If I recall correctly expiration is checked on access. So if the clocks are in sync with delta < unit I think it should work even for multiple-host setups. Separate fields are a good option for large(r) durations with are not multiple of a second (e.g. 29day+23h+59m+59s+999ms). To reuse the existing fields their type would need to change to vLong to hold this duration in ns. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
