Adar Dembo reassigned KUDU-605: ------------------------------- Assignee: (was: Adar Dembo) I never got around to doing this and am not actively working on it, so unassigning from myself. > Implement block placement hints > ------------------------------- > > Key: KUDU-605 > URL: https://issues.apache.org/jira/browse/KUDU-605 > Project: Kudu > Issue Type: Sub-task > Components: fs > Affects Versions: M5 > Reporter: Adar Dembo > Priority: Trivial > > The block managers need an API that lets users choose where blocks are > placed. Different block managers support different levels of granularity > (e.g. locality in the log block manager can refer to disks or containers), > and so we need to find a way to abstractly describe this stuff. > Some sample hints: > # As close as possible to block X > # As close as possible to <some opaque string> > # On disk A > # On disk A, B, or C > # On any disk > # Some combination of 1-2 and 3-5 (i.e. block locality + disk locality) -- This message was sent by Atlassian Jira (v8.3.4#803005)
