Example 66 with RingbufferConfig

use of com.hazelcast.config.RingbufferConfig in project hazelcast by hazelcast.

the class RingbufferTTLTest method whenTTLEnabled_thenVisibilityIsGuaranteed.

// if ttl is set, we need to make sure that during that period all items are accessible.
// In this particular test we set the ttl period to 10 second. The minimumVisibilitySeconds to
// give us an error margin of 2 seconds (due to threading etc... we don't want to have another
// spurious failing test.
