jerrypeng opened a new pull request #3237: fix bug involving consumer producer deadlock in functions
URL: https://github.com/apache/pulsar/pull/3237
 
 
   ### Motivation
   
   Fixed bug involving potential deadlock between consuming and producing in functions. In functions, if a consumer is blocked from consuming due to unacked number of messages and the producer is unable to produce messages successfully. Those messages will be timed out and never ack, but those messages will never be redelivered to the consumer because i was already blocked.
   
   Thus we should set the send timeout on the producer to be infinity to keep on try to send the message
