The recommended range for the threshold is [0.5, &#8230;&#8203;) with the default value of 1.0. The threshold represents a policy wrt what to prefer: either ideal balance of the cross-location load on per-table basis (lower threshold value) or minimum number of replica movements between locations (greater threshold value). The default value is empirically proven to be a good choice between 'ideal' and 'good enough' replica distributions.</p>
