    Description

      Introduce a new HLog configuration parameter (batchEntries) for more aggressive batching of appends. If this is enabled, HLog appends are not written to the HLog writer immediately, but batched and written either periodically or when a sync is requested. Because sync times become larger, they use delayed RPCs to free up RPC handler threads.
