Hui Fei updated HDDS-15121:
---------------------------
Target Version/s: 2.3.0 (was: 2.2.0)
> Unify SCM list container on SCMListContainerRequestProto
> --------------------------------------------------------
>
> Key: HDDS-15121
> URL: https://issues.apache.org/jira/browse/HDDS-15121
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Sarveksha Yeshavantha Raju
> Assignee: Sarveksha Yeshavantha Raju
> Priority: Major
> Labels: pull-request-available
>
> h1. Problem
> The SCM list container API is split across multiple overloads, with each
> variant adding another parameter for filtering.
> h1. Drawbacks
> * Does not scale with new filters - Adds more overloads, forces some filters
> to exist only on one overload, so callers must pass unrelated parameters as
> null / defaults.
>
> * Duplicated javadoc - Each overload carries similar Javadoc.
> h1. Solution
> A *unified query object* (or single listContainers(proto) plus optional
> fields on SCMListContainerRequestProto)
> One server implementation that interprets that object, applies filters,
> applies the cluster max-count cap, and returns a page.
> New filters become new optional fields on the same request type - no new RPC
> name, no new overload matrix.
