-----------------------------------------
Summary: Automatic and near real-time healing of locality
Key: HBASE-26250
URL: https://issues.apache.org/jira/browse/HBASE-26250
Project: HBase
Issue Type: New Feature
Reporter: Bryan Beaudreault
I’m proposing a somewhat major new tool for quickly and efficiently alleviating
latency pains due to locality. This is especially useful in cloud environments,
and has been highly impactful at HubSpot, where we run thousands of
RegionServers across 40+ multi-zone clusters. Please see the attached design
doc for details on the problem, why compactions are not enough to solve the
problem, and an overview (with diagram) of the components that make up this new
tool.
As spec'd, this new feature would require submission of a new tool in the HDFS
project. Once we reach consensus on the approach I can create the relevant
upstream HDFS JIRA.
See the design doc here:
