3. 应用调用API syncForwardToPeer，如果vnode B是slave状态，sync模块将包含WAL Head的数据包通过Forward消息发送给vnode B，否则就不转发。
4. vnode B收到Forward消息后，调用回调函数writeToCache, 交给应用处理
5. vnode B应用在写入成功后，都需要调用syncAckForward通知sync模块已经写入成功。
6. 如果quorum大于1，vnode B需要等待应用的回复确认，收到确认后，vnode B发送Forward Response消息给node A。

不同之处：
- 选举流程不一样：Raft里任何一个节点是candidate时，主动向其他节点发出vote request, 如果超过半数回答Yes, 这个candidate就成为Leader,开始一个新的term. 而TDengine的实现里，节点上线、离线或角色改变都会触发状态消息在节点组类传播，等节点组里状态稳定一致之后才触发选举流程，因为状态稳定一致，基于同样的状态信息，每个节点做出的决定会是一致的，一旦某个节点符合成为master的条件，无需其他节点认可，它会自动将自己设为master。TDengine里，任何一个节点检测到其他节点或自己的角色发生改变，就会给节点组内其他节点进行广播的。Raft里不存在这样的机制，因此需要投票来解决。

- 对WAL的一条记录，Raft用term + index来做唯一标识。但TDengine只用version（类似index)，在TDengine实现里，仅仅用version是完全可行的, 因为TDengine的选举机制，没有term的概念。
如果整个虚拟节点组全部宕机，重启，但不是所有虚拟节点都上线，这个时候TDengine是不会选出master的，因为未上线的节点有可能有最高version的数据。而RAFT协议，只要超过半数上线，就会选出Leader。

对于采集的数据，一般有保留时长，这个时长由系统配置参数keep决定。超过这个设置天数的数据文件，将被系统自动删除，释放存储空间。
给定days与keep两个参数，一个vnode总的数据文件数为：keep/days。总的数据文件个数不宜过大，也不宜过小。10到100以内合适。基于这个原则，可以设置合理的days。 目前的版本，参数keep可以修改，但对于参数days，一但设置后，不可修改。
给定days与keep两个参数，一个典型工作状态的vnode中总的数据文件数为：`向上取整(keep/days)+1`个。总的数据文件个数不宜过大，也不宜过小。10到100以内合适。基于这个原则，可以设置合理的days。 目前的版本，参数keep可以修改，但对于参数days，一但设置后，不可修改。
在每个数据文件里，一张表的数据是一块一块存储的。一张表可以有一到多个数据文件块。在一个文件块里，数据是列式存储的，占用的是一片连续的存储空间，这样大大提高读取速度。文件块的大小由系统参数maxRows（每块最大记录条数）决定，缺省值为4096。这个值不宜过大，也不宜过小。过大，定位具体时间段的数据的搜索时间会变长，影响读取速度；过小，数据块的索引太大，压缩效率偏低，也影响读取速度。

- 时间可以加减，比如 now-2h，表明查询时刻向前推 2 个小时（最近 2 小时）。数字后面的时间单位可以是 u(微秒)、a(毫秒)、s(秒)、m(分)、h(小时)、d(天)、w(周)。 比如 `select * from t1 where ts > now-2w and ts <= now-1w`，表示查询两周前整整一周的数据。在指定降频操作（down sampling）的时间窗口（interval）时，时间单位还可以使用 n(自然月) 和 y(自然年)。

```
以自动建表的方式，同时向表tb1_name和tb2_name中按列分别插入多条记录。
说明：`(tb1_field1_name, ...)`的部分可以省略掉，这样就是使用全列模式写入——也即在 VALUES 部分提供的数据，必须为数据表的每个列都显式地提供数据。全列写入速度会远快于指定列，因此建议尽可能采用全列写入方式，此时空列可以填入NULL。
从 2.0.20.5 版本开始，子表的列名可以不跟在子表名称后面，而是可以放在 TAGS 和 VALUES 之间，例如像下面这样写：
```mysql
INSERT INTO tb1_name [USING stb1_name TAGS (tag_value1, ...)] (tb1_field1_name, ...) VALUES (field1_value1, ...) (field1_value2, ...) ...;
