> h3. *Motivation*
> In https://issues.apache.org/jira/browse/IGNITE-19735 I have tried to extends MetaStorageManager api with 
> {code:java}
> void registerPrefixWatch(ByteArray key, long startRevision, WatchListener lsnr){code}
>  method for the watch listeners receive the events with revision lower than the applied revision. The KeyValueStorage#watchRange method already has a start revision number so the issue seems easy. But I have written a test and see that the watch listener receives events with revisions which are grater than the applied revision only. See https://github.com/gridgain/apache-ignite-3/tree/ignite-19735_1 and test ItMetaStorageWatchTest#testWatchWithOldStartRevision.
> h3. *Definition of Done*
> Watch listeners which were registered with a start revision lower that the applied revision must receive all events from a start revision.
