Hello Ashwani Raina, Yingchun Lai, Yifan Zhang, Kudu Jenkins, Abhishek Chennaka,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/20797
to look at the new patch set (#3).
Change subject: [rpc] increase listened socket backlog up to 512
......................................................................
[rpc] increase listened socket backlog up to 512
This patch updates the default value for --rpc_acceptor_listen_backlog,
setting it up to 512 by default. This is to help busy Kudu servers
accommodating of larger bursts of incoming requests for new RPC
connections. In addition, a warning message is output into the log
if the setting for the flag is effectively capped by the system-level
limit.
I manually verified that the warning is issued as expected on Linux and
macOS, correspondingly:
--rpc_acceptor_listen_backlog setting 512 is capped at 128 by
/proc/sys/net/core/somaxconn
--rpc_acceptor_listen_backlog setting 512 is capped at 256 by
kern.ipc.somaxconn
