As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) Ansible YAML source code syntax highlighting (style: standard
) with prefixed line numbers.
Alternatively you can here view
the uninterpreted source code file.
3 - Added a new config option ``scheduler_weight_handler``. This is a global
4 option which specifies how the scheduler should choose from a listed of
5 weighted pools. By default the existing weigher is used which always
6 chooses the highest weight.
7 - Added a new weight handler ``StochasticHostWeightHandler``. This weight
8 handler chooses pools randomly, where the random probabilities are
9 proportional to the weights, so higher weighted pools are chosen more
10 frequently, but not all the time. This weight handler spreads new
11 shares across available pools more fairly.
