Sean Busbey commented on HBASE-12848: ------------------------------------- I've been working through actually using this feature and the more I do so the more convinced I am that this should all be a configuration walkthrough in the ref guide coupled with enhancement requests to the HDFS project. (as opposed to code in HBase as we're currently doing.) > Utilize Flash storage for WAL > ----------------------------- > > Key: HBASE-12848 > URL: https://issues.apache.org/jira/browse/HBASE-12848 > Project: HBase > Issue Type: Sub-task > Reporter: Ted Yu > Assignee: Ted Yu > Fix For: 2.0.0, 1.1.0 > > Attachments: 12848-v1.patch, 12848-v2.patch, 12848-v3.patch, > 12848-v4.patch, 12848-v4.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
