### Motivation Current the [[cacheEvictionTask](https://github.com/apache/pulsar/blob/4532c15ea705d7b88274025beb1c4913e5069d64/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerFactoryImpl.java#L255)](https://github.com/apache/pulsar/blob/4532c15ea705d7b88274025beb1c4913e5069d64/managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/ManagedLedgerFactoryImpl.java#L255) will be executed periodically, the period is calculated by ```java double evictionFrequency = Math.max(Math.min(config.getCacheEvictionFrequency(), 1000.0), 0.001); long waitTimeMillis = (long) (1000 / evictionFrequency); ``` And this task will be executed once and then sleep `waitTimeMillis` before next round. We can do some optimize for this logic. ### Modifications 1. Set the cache eviction task interval directly by addint a new configuration `managedLedgerCacheEvictionIntervalMs` 2. use a `ScheduledExecutorService` to execute the cache eviction task every `managedLedgerCacheEvictionIntervalMs` ### Verifying this change This change is already covered by existing tests, such as *(please describe tests)*. - ### Does this pull request potentially affect one of the following parts: *If `yes` was chosen, please highlight the changes* - Dependencies (does it add or upgrade a dependency): ( no) - The public API: (no) - The schema: (no ) - The default values of configurations: ( no) - The wire protocol: (no) - The rest endpoints: (no) - The admin cli options: (no) - Anything that affects deployment: (no) ### Documentation - [ ] `no-need-doc` (Please explain why) -- This is an automated message from the Apache Git Service.
