be seen that some limitations of ETCD v2: The expiration time can only be set to each key, if more than one key to ensure that the life cycle of consistency is more difficult. Watch can only watch one key and its child nodes (via parameter recursive), and cannot perform multiple watch. It is difficult to use the watch mechanism to achieve complete data synchronization (risk of loss of change), so most of the current usage is through watch to know the changes, and then retrieve the d

City record is deleted from the database. after testing, the database reads and writes too frequently, resulting in too much consumption and low efficiency. 3. after analysis, we decided to adopt KVDB, with extremely fast read/write speeds. it took about 5 seconds to load two thousand six hundred pieces of data. The code is as follows: code for loading the City ID, named KV. php: */getData ($ SQL); // retrieve all city information from the database $
