------------------------------
Summary: Utilize Flash storage for WAL
Key: HBASE-12848
URL: https://issues.apache.org/jira/browse/HBASE-12848
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
One way to improve data ingestion rate is to make use of Flash storage.
HDFS is doing the heavy lifting - see HDFS-7228.
We assume an environment where:
1. Some servers have a mix of flash, e.g. 2 flash drives and 4 traditional
drives.
2. Some servers have all traditional storage.
3. RegionServers are deployed on both profiles within one HBase cluster.
This JIRA allows WAL to be managed on flash in a mixed-profile environment.
