dlg99 opened a new pull request #1088: ISSUE #1086 (@bug W-4146427@) Client-side backpressure in netty (Fixe?
URL: https://github.com/apache/bookkeeper/pull/1088
 
 
   ?s: io.netty.util.internal.OutOfDirectMemoryError under continuous heavy load)
   
   Descriptions of the changes in this PR:
   
   Added client-side support for netty backpressure.
   Now PCBC will actually respect netty's behavior configured with
   clientWriteBufferLowWaterMark and clientWriteBufferHighWaterMark config parameters.
   It is highly recommended setting them reasonably high for expected size of requests and load
   Otherwise client may end up doing frequent waits / throughput may drop.
        
   Master Issue: #1086
