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 Change-Id: Ib6f5791acad6ea0787e23d4c71ab2a7ac4c8c1f2 Reviewed-on: http://gerrit.cloudera.org:8080/20797 Tested-by: Kudu Jenkins Reviewed-by: Abhishek Chennaka <[email protected]> --- M src/kudu/rpc/acceptor_pool.cc M src/kudu/rpc/acceptor_pool.h M src/kudu/rpc/messenger.cc M src/kudu/rpc/messenger.h M src/kudu/server/server_base.cc 5 files changed, 135 insertions(+), 13 deletions(-) Approvals: Kudu Jenkins: Verified Abhishek Chennaka: Looks good to me, approved -- To view, visit http://gerrit.cloudera.org:8080/20797 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: merged Gerrit-Change-Id: Ib6f5791acad6ea0787e23d4c71ab2a7ac4c8c1f2 Gerrit-Change-Number: 20797 Gerrit-PatchSet: 5 Gerrit-Owner: Alexey Serbin <[email protected]> Gerrit-Reviewer: Abhishek Chennaka <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Ashwani Raina <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Yifan Zhang <[email protected]> Gerrit-Reviewer: Yingchun Lai <[email protected]>
