阿狸先森|聊聊claudb的server command( 二 ) 序本文主要研究一下claudb的servercomm

slaves(Database adminDatabase) {DatabaseValue value = http://kandian.youth.cn/index/adminDatabase.getOrDefault(safeKey("slaves"), DatabaseValue.EMPTY_SET);ImmutableList set = value.getSet().asList().sort(SafeString::compareTo);return set.map(SafeString::toString).map(slave -> slave.split(":")).map(slave -> array(string(slave[0]), string(slave[1]), string("0"))).asList();}}

RoleCommand实现了DBCommand接口，其execute方法先获取serverState及adminDatabase ，然后根据serverState.isMaster()返回master(adminDatabase)或slave(adminDatabase)

【阿狸先森|聊聊claudb的server command】

@Command("flushdb")public class FlushDBCommand implements DBCommand {?@Overridepublic RedisToken execute(Database db, Request request) {db.clear();return responseOk();}}

FlushDBCommand实现了DBCommand接口，其execute方法执行db.clear()

@Command("dbsize")public class DatabaseSizeCommand implements DBCommand {@Overridepublic RedisToken execute(Database db, Request request) {return integer(db.size());}}
