Adar Dembo resolved KUDU-2582. ------------------------------ Resolution: Information Provided Fix Version/s: NA This is indeed a known issue in Kudu, and one of several reasons why Kudu performs suboptimally for UPDATE-heavy workloads. In any case, Jira isn't the right medium for open-ended discussion like this; please e-mail [u...@kudu.apache.org|mailto:u...@kudu.apache.org], or join the Kudu Slack community. > Locks are acquired to cost much time in transactions > ---------------------------------------------------- > > Key: KUDU-2582 > URL: https://issues.apache.org/jira/browse/KUDU-2582 > Project: Kudu > Issue Type: Bug > Reporter: xiaokai.wang > Priority: Major > Fix For: NA > > > Hi guys, I met a problem about the keys locks that almost impacts the service > normal writing. > As we all know, a transaction which get all row_key locks will go on next > step in kudu. Everything looks good, if keys are not concurrent updated. But > when keys are updated by more than one client at the same time, locks are > acquired to wait much time. The cases are often in my product environment. > Does anybody meet the problem? Has any good ideal for this? > Thanks. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
