sivabalan narayanan closed HUDI-5433. ------------------------------------- Resolution: Fixed > Fix the way we deduce the pending instants for MDT writes > --------------------------------------------------------- > > Key: HUDI-5433 > URL: https://issues.apache.org/jira/browse/HUDI-5433 > Project: Apache Hudi > Issue Type: Bug > Components: metadata > Reporter: sivabalan narayanan > Assignee: sivabalan narayanan > Priority: Blocker > Labels: pull-request-available > Fix For: 0.13.0 > > > we trigger compaction in MDT, only when there are no pending inflights apart > from the one thats currently updating the MDT. So we use below code snippet > for it. > > {code:java} > List<HoodieInstant> pendingInstants = > dataMetaClient.reloadActiveTimeline().filterInflightsAndRequested() > .findInstantsBefore(instantTime).getInstants(); {code} > As you could see, we use "findInstantsBefore" which could not yield right > results at all times. > > So, we need to find all inflight instants and see if there are any except the > current commit thats updating the MDT. If there are any, we should defer > compaction. > Impact: > writes to MDT might fail if there was any missed inflight and later it was > rolledback. Users have to disable MDT and make progress. -- This message was sent by Atlassian Jira (v8.20.10#820010)
