By comparing the two heatmaps, you can see the differences in the routes as well as notice differences in the pacing. Third, if you have identical chunks of data next to each other on adjacent rows, then Bigtable can compress the data. Kubernetes add-on for managing Google Cloud resources. The row key Of course, you could use more than 3 numbers and hope that it works well in most cases, but theres another, potentially bigger issue. If a query requested multiple records over a time period, then your code would have to run separate scans for each salt value and combine the results, which would be a real pain. The main decision to make is how to group them in column families. balloon, over the course of a week. serialized format such as a protocol buffer (protobuf).
