`static long`	`getExpectedRetentionTimeInMs(Store store, HybridStoreConfig hybridConfig)`	The default retention time for the RT topic is defined in `PubSubConstants.DEFAULT_TOPIC_RETENTION_POLICY_MS`, but if the rewind time is larger than this, then the RT topic's retention time needs to be set even higher, in order to guarantee that buffer replays do not lose data.

public static long getExpectedRetentionTimeInMs(Store store,
                                                HybridStoreConfig hybridConfig)
```
    The default retention time for the RT topic is defined in PubSubConstants.DEFAULT_TOPIC_RETENTION_POLICY_MS, but if the rewind time is larger than this, then the RT topic's retention time needs to be set even higher, in order to guarantee that buffer replays do not lose data. In order to achieve this, the retention time is set to the max of either: 1. PubSubConstants.DEFAULT_TOPIC_RETENTION_POLICY_MS; or 2. HybridStoreConfig.getRewindTimeInSeconds() + Store.getBootstrapToOnlineTimeoutInHours() + 172800000L; This is a convenience function, and thus must be ignored by the JSON machinery.
    
    Returns:
    
    the retention time for the RT topic, in milliseconds.
