* And therefore has an complex lua-scripts inside.</p>
*
* <p>Current redis implementation doesnt have map entry eviction functionality.
* Thus entries are checked for TTL expiration during any key/value/entry read operation.
* If key/value/entry expired then it doesn't returns and clean task runs asynchronous.
* Clean task deletes removes 100 expired entries at once.
* In addition there is {@link org.redisson.eviction.EvictionScheduler}. This scheduler
* deletes expired entries in time interval between 5 seconds to 2 hours.</p>
*
* <p>If eviction is not required then it's better to use {@link RedissonMap} object.</p>
