> This is a predecessor for optimizing performance of
> {{ResourceAllocationStrategy}} (FLINK-21174).
> To optimize the performance, we will need to build and maintain index for
> registered/pending resources. As the strategy is designed to be stateless, we
> propose to build and maintain the index at {{TaskManagerTracker}}, providing
> only access methods to the strategy.
> To decouple index accessing from the common {{FineGrainedSlotManager}}
> workflow, while preventing the strategy from directly modifying the states,
> we can introduce a read-only interface of {{TaskManagerTracker}} and pass it
> to the strategy. In this way, we can easily extend the read-only interface to
> provide more index-accessing methods in future.
