> HBASE-8329 recently introduced on all branches {{double
> RegionServerServices#getCompactionPressure()}}, which returns a value greater
> than or equal to 0.0, and any value greater than 1.0 means we have exceeded
> the store file limit on some stores. It could be reasonable to send this
> value along in server load statistics (clamping max at 1.0), and consider it
> as an additional term in the ExponentialClientBackoffPolicy.
