             Summary: NettyAvroRpcClient.configure() prevents timeouts less than one second
                 Key: AVRO-1712
                 URL: https://issues.apache.org/jira/browse/AVRO-1712
             Project: Avro
          Issue Type: Improvement
          Components: java
    Affects Versions: 1.7.7
            Reporter: Todd Baldwin
            Priority: Minor


The NettyAvroRpcClient prevents connection or request timeouts less than one second.  I would
like to remove this restriction.  I'm hoping to specify values down to around the tens-of-millisecond
ranges.

My actual use case is log4j/Flume with Load-Balancing Log4jAppender using Avro.  I have 50
clients hosts sending to 70 Flume collectors.  Under high load, log4j/Flume can spend a long
time in timeouts to multiple destinations with the 1 second request/connect timeouts.  I would
like to bring the NettyAvroRpcClient timeouts down into the 50 millisecond-or-so range to
help avoid buffer overflows when one or more destinations are down.
