> 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
> Priority: Major
> Fix For: 3.0.0, 2.2.0, 1.5.1
>
> Attachments: HBASE-21301.v0.master.patch
>
>
> 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.
