Maxim Muzafarov updated IGNITE-9913: ------------------------------------ Ignite Flags: Release Notes Required > Prevent data updates blocking in case of backup BLT server node leave > --------------------------------------------------------------------- > > Key: IGNITE-9913 > URL: https://issues.apache.org/jira/browse/IGNITE-9913 > Project: Ignite > Issue Type: Improvement > Components: general > Reporter: Ivan Rakov > Assignee: Anton Vinogradov > Priority: Major > Fix For: 2.8 > > Attachments: 9913_yardstick.png, master_yardstick.png > > Time Spent: 6h > Remaining Estimate: 0h > > Ignite cluster performs distributed partition map exchange when any server > node leaves or joins the topology. > Distributed PME blocks all updates and may take a long time. If all > partitions are assigned according to the baseline topology and server node > leaves, there's no actual need to perform distributed PME: every cluster node > is able to recalculate new affinity assigments and partition states locally. > If we'll implement such lightweight PME and handle mapping and lock requests > on new topology version correctly, updates won't be stopped (except updates > of partitions that lost their primary copy). -- This message was sent by Atlassian Jira (v8.3.4#803005)
