Description

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.
