---------------------------------------
Summary: Change the location prefetch
Key: HBASE-10018
URL: https://issues.apache.org/jira/browse/HBASE-10018
Project: HBase
Issue Type: Bug
Affects Versions: 0.96.0, 0.98.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Priority: Minor
Fix For: 0.98.0, 0.96.1
Issues with prefetching are:
- we do two calls to meta: one for the exact row, one for the prefetch
- it's done in a lock
- we take the next 10 regions. Why 10, why the 10 next?
- is it useful if the table has 100K regions?
Options are:
- just remove it
- replace it with a reverse scan: this would save a call
