Mysql pagination query optimization

First create a database test, and then create a table devices, (here to create multiple fields to demonstrate the effect)

CREATE TABLE `devices`  (
  `id` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT '',
  `TVName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVModelNumber` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVSerialNumber` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVRoomID` int(11) DEFAULT NULL,
  `TVMACAddress` varchar(17) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVIPAddress` varchar(15) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `VSecureTVID` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `Type` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `PowerStatus` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVUniqueID` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `FirmwareId` int(11) DEFAULT NULL,
  `CloneId` int(11) DEFAULT NULL,
  `LastCloneRename` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT '{\"old\":\"Unknown\",\"new\":\"Unknown\"}',
  `Status` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `Progress` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `TVStatus` text CHARACTER SET utf8 COLLATE utf8_general_ci,
  `si_clone_Identifiers` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `si_firmware_Identifier` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `tv_clone_Identifiers` varchar(8000) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `tv_firmware_Identifier` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `success_siclone_Identifier` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `success_tvclone_Identifier` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `clone_color` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT 'black',
  `fw_color` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT 'black',
  `CreatedDate` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `ModifiedDate` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `Lastonline` varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `clone_mode` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL DEFAULT 'Upgrade',
  `upload_progress` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT 'ST',
  `upload_session_id` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `upload_session_start` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `upload_session_end` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `upload_session_status` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `channel_color` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `app_color` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `upgrade_type` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `si_Identifiers` text CHARACTER SET utf8 COLLATE utf8_general_ci,
  `networkInterfaceIp` varchar(15) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
  `clone_type` varchar(45) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT 'None',
  PRIMARY KEY (`id`) USING BTREE,
  INDEX `FirmwareId`(`FirmwareId`) USING BTREE,
  INDEX `CloneId`(`CloneId`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

I want to add 8000 data to devices in this table.

SELECT * FROM `devices` limit 7000,10 # 0.015s The time consumed here is 0.015s

select * from `devices` where id> (select id from devices limit 7000,1) limit 10 # 0.002s The time consumed here is 0.002s

Same paging query, different time consumption

to be continued…
