---------------------------------------
Summary: Heatmap for key access patterns
Key: HBASE-21301
URL: https://issues.apache.org/jira/browse/HBASE-21301
Project: HBase
Issue Type: Improvement
Reporter: Archana Katiyar
Assignee: Archana Katiyar
Google recently released a beta feature for Cloud Bigtable which presents a
heat map of the keyspace. *Given how hotspotting comes up now and again here,
this is a good idea for giving HBase ops a tool to be proactive about it.*
>>>
Additionally, we are announcing the beta version of Key Visualizer, a
visualization tool for Cloud Bigtable key access patterns. Key Visualizer helps
debug performance issues due to unbalanced access patterns across the key
space, or single rows that are too large or receiving too much read or write
activity. With Key Visualizer, you get a heat map visualization of access
patterns over time, along with the ability to zoom into specific key or time
ranges, or select a specific row to find the full row key ID that's responsible
for a hotspot. Key Visualizer is automatically enabled for Cloud Bigtable
clusters with sufficient data or activity, and does not affect Cloud Bigtable
cluster performance.
