Hello HBase masters, I am wondering whether in current implementation, each client of HBase cache all information of region server, for example, where is region server (physical hosting machine of region server), and also cache row-key range managed by the region server. If so, two more questions,
- will there be too much overhead (e.g. memory footprint) of each client? - when such information is downloaded and cached at client side, and when the information is refreshed (does it only triggered by region server change and failure to fetch such information from client -- e.g. when client use cache to access machine A for region B, but find nothing, so the client needs to refresh the information in cache to see which machine owns region B)? regards, Lin
