[GitHub] [ozone] linyiqun commented on pull request #1780: HDDS-3205. DeleteBlock via Ratis in SCM HA

   Sorry for the late comments.
   
   I have one concern about current SCM HA handling mechanism. As the Blocks/Container/Pipeline update ops are cached in BatchOperation, and only be flushed during SCM snapshot take. But if user use the stand alone SCM mode to run based on current HA code. Is that will lead OOM error since stand alone SCM won't take any snapshot by itself while the request update will still go into SCM Transaction  Buffer in our current implementation.
   
   @runzhiwang @GlenGeng , is this a real problem of my concern?
