Alexey Serbin created KUDU-2937: ----------------------------------- Summary: built-in NTP client: implement 'iburst' Key: KUDU-2937 URL: https://issues.apache.org/jira/browse/KUDU-2937 Project: Kudu Issue Type: Sub-task Reporter: Alexey Serbin
For fast initial synchronisation with NTP sources it's necessary to implement iburst-like behavior. >From [RFC5905|https://tools.ietf.org/html/rfc5905] : {noformat} If the BURST flag is lit and the server is reachable and a valid source of synchronization is available, the client sends a burst of BCOUNT (8) packets at each poll interval. The interval between packets in the burst is two seconds. This is useful to accurately measure jitter with long poll intervals. If the IBURST flag is lit and this is the first packet sent when the server has been unreachable, the client sends a burst. This is useful to quickly reduce the synchronization distance below the distance threshold and synchronize the clock. {noformat} -- This message was sent by Atlassian Jira (v8.3.2#803003)
