RegionInfoAccessor is used to collect all regions’ information on this TiKV into a collection so that other parts of TiKV can get region information from it. It registers a observer to raftstore, which is named RegionEventListener. When the events that we are interested in happen (such as creating and deleting regions), RegionEventListener simply sends the events through a channel. In the mean time, RegionCollector keeps fetching messages from the channel, and mutates the collection according to the messages. When an accessor method of RegionInfoAccessor is called, it also simply sends a message to RegionCollector, and the result will be sent back through as soon as it’s finished. In fact, the channel mentioned above is actually a util::worker::Worker.

Caution: Note that the information in RegionInfoAccessor is not perfectly precise. Some regions may be temporarily absent while merging or splitting is in progress. Also, RegionInfoAccessor’s information may slightly lag the actual regions on the TiKV. RaftStoreEvent Represents events dispatched from raftstore coprocessor.
