 Description   

Until now the knob shard-snapshot-chunk-size was used to determine
the max size of snapshot chunks as well as AppendEntries messages.
These objects however play roles in two different processes:

  • snapshot capture and installation
  • journal replication

Adding a separate config knob for the max size of AppendEntries messages will allow the user to tweak the two systems independently and more precisely.
