| # PIP-357: Correct the conf name in load balance module. |
| |
| # Background knowledge |
| |
| We use `loadBalancerBandwithInResourceWeight` and `loadBalancerBandwithOutResourceWeight` to calculate the broker's load in the load balance module. However, the correct conf name should be `loadBalancerBandwidthInResourceWeight` and `loadBalancerBandwidthOutResourceWeight`. This PIP is to correct the conf name in the load balance module. |
| |
| # Motivation |
| |
| The current conf name is incorrect. |
| |
| |
| # Detailed Design |
| |
| - deprecated `loadBalancerBandwithInResourceWeight` and `loadBalancerBandwithOutResourceWeight` in the load balance module. |
| - add `loadBalancerBandwidthInResourceWeight` and `loadBalancerBandwidthOutResourceWeight` in the load balance module. |
| |
| In case of users upgrading to this version don't notice the change, we will still support the old conf name in following way: |
| - If a configuration is not the default configuration, use that configuration. |
| - If both the new and the old are configured different from the default value, use the new one. |
| |
| # Backward & Forward Compatibility |
| |
| Backward compatible, users can upgrade to this version without doing any changes and the old conf name will still work. |
| If user want to use the new conf name, they can change the conf name in the configuration file. |
| Just remember that if both the new and the old are configured different from the default value, the new one will be used. |
