---------------------------------
Summary: Spread metadata across multiple data directories
Key: KUDU-2117
URL: https://issues.apache.org/jira/browse/KUDU-2117
Project: Kudu
Issue Type: Bug
Components: fs, tablet, tserver
Affects Versions: 1.6.0
Reporter: Andrew Wong
Assignee: Andrew Wong
Fix For: 1.6.0
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.
