Andrew Wong updated KUDU-2117: ------------------------------ Issue Type: Improvement (was: Bug) > Spread metadata across multiple data directories > ------------------------------------------------ > > Key: KUDU-2117 > URL: https://issues.apache.org/jira/browse/KUDU-2117 > Project: Kudu > Issue Type: Improvement > Components: fs, tablet, tserver > Affects Versions: 1.6.0 > Reporter: Andrew Wong > Assignee: Andrew Wong > Priority: Major > > Tablet metadata and consensus metadata are placed in the first configured > data directory. This is an issue, as every write to these metadata incurs an > fsync and this stresses the first disk considerably more than the others > One way around this is to spread metadata across multiple data directories. A > natural choice would be to place them in a directory within the tablet's disk > group. In this way, the data/metadata can be completely localized to the disk > group, which has the added benefit of making the risk of disk failures easier > to assess per tablet. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
