> * Currently incremental replication flow of hive dumps all events read from
> notification logs sequentially in staging directory.
> * Repl Load loads all the event directories present in staging directory to
> a list and processes them.
> * This has caused O.O.M issues when number of events are large.
> Hence introducing batching of events where Repl Dump dumps events in batches
> and Repl Load processes events batch by batch to avoid O.O.M.
