> refactor loadbalance filters logic to support invocation based filter
> ---------------------------------------------------------------------

> Key: SCB-706
> URL: https://issues.apache.org/jira/browse/SCB-706
> Project: Apache ServiceComb
> Issue Type: Improvement
> Reporter: liubao
> Assignee: liubao
> Priority: Major

> Why we do this?
> # When implement invocation based filter, e.g. darklaunch deployment, we
> need to filter servers based on invocation parameters. But now, we create a
> Loadbalaner instance for each service, and Robin filter interface can not
> pass Invocation to it. Before refactor, we doing this by ThreadLocal and
> cache Invocation, and use in filter implementation. This is error prone and
> users can't handle this complixity
> # We have other improvements, e.g. SCB-700, we can do server status check,
> and add a filter a choose from active servers. We need to consider filter
> orders and other feature, current implementation not satisfy this.
> # We want to make loadbalance code handy by remove some compatible fixes.
