Examples of ZKTable

com.alibaba.wasp.zookeeper.ZKTable
Helper class for table state tracking for use by {@link com.alibaba.wasp.master.AssignmentManager}. Reads, caches and sets state up in zookeeper. If multiple read/write clients, will make for confusion. Read-only clients other than AssignmentManager interested in learning table state can use the read-only utility methods in {@link ZKTableReadOnly}.
To save on trips to the zookeeper ensemble, internally we cache table state.
