The digram is with minor errors that fileBaseWriter itself contains only SSTWriter, that is, it should not be allowed by a processor other than sstProcessor after consulting @Nicole00 :)

This is worthy mentioned in metrics documentation:
It turns out that stats like num_add_vertices.sum.3600 are not actually vertices count, instead, it's the insert count when the batch size of the insert query is not 1, also, in & out also should be aware of in this case.
Thus, the SUM of num_add_vertices.sum.3600 of all storageD instances is not the actual vertices added of the corresponding period.
https://discuss.nebula-graph.com.cn/t/topic/4880/10?u=wey
Which I quoted @laura-ding 's clarification as below:
现在 metric 统计的 edge 和 vertex 的数量是向storage批量写入的次数，所以当你插入的query含有batch的时候，这个统计就不是实际的点边数量，而是batch数量（当然，边点时候，还有包含每条边的反向边）。假如你每个insert 语句只包含一个点或者一条边，那么，你把集群所有storage统计出来的数据就是点的插入数量，边的话，需要用总数除以2（因为有反向边）

should clarify if the config would change after run rpm command.
I prefer use command rpm2cpio, then move the binary manually.

Maybe apart from the highlight, also to point out the mitigation(like to use UNION instead as @bright-starry-sky suggested?)
Thanks!
This was triggered by @Shylock-Hg, who shared the function datasetrowcol() in the forum, thanks @Shylock-Hg !!!
Should we review new functions that are worth exposing to end-users?

Thanks!
Description naming rules for nGQL, such as space_name, tag_name, vertex_name, edge_name, prop_name. It just can include character, number, underline !?

可以在CREATE SPACE时设置replica_factor为偶数（例如设置为2）吗？

We could consider adding an alias to the latest version of docs, this is helpful when we would like to refer some chapters(that's basically not changed among versions) always to its latest version.
This was triggered in discussion in this PR vesoft-inc/nebula#2476. cc @jamieliu1023 @yihong0618
It's feasible via https://squidfunk.github.io/mkdocs-material/setup/setting-up-versioning/#publishing-a-new-version, which I quote as below:
Publishing a new version¶
If you want to publish a new version of your project documentation, choose a version identifier and update the alias set as the default version with:
mike deploy --push --update-aliases 0.1 latest
Note that every version will be deployed as a subdirectory of your site_url, e.g.:
mike set-default --push latest
Thanks.

as titled, it's still delivered in binary packages, should corresponding chapters in 1.x be uplifted?

问题: exchange --hive 参数默认是 false, 文档写的 true.
直接用中文吧:)
我发现 nebula 中文文档在一些地方会有着英语风格不统一的问题。
举个例子：
在升级历史版本到 v2.0.0之中
前面的 Storaged 的前后都会有空格，而在下文中的 Storaged 的前后却没有空格，这样会显得文档整体非常的乱 : )
和这个差不多的有挺多地方 😏
不如一起改一改？: )😏

Test the Studio docs for 2.2.0. If they are OK, release them.
As title.

It looks good in the GitHub preview though.
It should be local_config instead of local-config
https://docs.nebula-graph.com.cn/2.0.1/8.service-tuning/compaction/#_1
It's easy for users to write:
incorrect
match path=(n:player{name: "Tim Duncan"})-[e:follow*1..2]-(m) \
where e.degree > 0 \
return path
rather than:
correct
match path=(n:player{name: "Tim Duncan"})-[e:follow*1..2]-(m) \
where ALL(e_ in e WHERE e_.degree > 0) \
return path
Could we put the correct expression somewhere(and in a highlighted way) in docs?
https://docs.nebula-graph.com.cn/master/3.ngql-guide/7.general-query-statements/2.match/
MATCH <pattern> [<WHERE clause>] RETURN <output>
https://docs.nebula-graph.com.cn/2.0.1/3.ngql-guide/8.clauses-and-options/with/
example2
MATCH p=(v:player{name:"Tim Duncan"})--() \
WITH nodes(p) AS n \
UNWIND n AS n1 \
RETURN DISTINCT n1;
In Example2 'with', 'unwind' is not a part of pattern, so should the syntax of match be added?
It seems some old docs pages are with higher ranks in Google(which is normal) [1], could we possibly add warning info to avoid user refers to them wrongly as we did in those non-latest docs with the version in URL [2]?

Error below when typing $make following the doc
... FTIndexExecutor.cpp line 83 ... ‘shmId’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
I add the following line at the beginning of src/executor/maintain/FTIndexExecutor.cpp
_Pragma ("GCC diagnostic ignored "-Wmaybe-uninitialized"")
and it works.
As shown in the picture, the white font could not be displayed.
I modified the logo font to look like the following :
Dear,
From match-tag, it's stated that:
Tag的索引和属性的索引不同。如果Tag的某个属性有索引，但是Tag本身没有索引，用户无法基于该Tag执行MATCH语句。
While in create index, it mentioned that:
如果已经为"某个Tag T的属性A"建立过属性索引i_TA，则没有必要对于Tag T额外再建立一个Tag索引i_T。这是因为查询引擎可以使用i_TA来替代i_T。Edge type索引同理。但是，i_T却不能替代i_TA用于属性查找。
How should I understand this, please?
Thanks!
BR, Wey
使用默认值。
CREATE SPACE my_space_1;指定分片数量。
CREATE SPACE my_space_2(partition_num=10);指定副本数量。
CREATE SPACE my_space_3(replica_factor=1); 以上方法都报错

The code is just like this:
UPSERT VERTEX 111 SET player.name = "Dwight Howard", player.age = $^.player.age + 11 WHEN $^.player.name == "Ben Simmons" && $^.player.age > 20 YIELD $^.player.name AS Name, $^.player.age AS Age;

now
nebula> CREATE EDGE follow (degree, int);
expected
nebula> CREATE EDGE follow (degree int);
It's found some backticks fenced code blocks under the - separated lists were indented.
For the reason indentation itself is the semantics of the basic code block, thus the backticks fenced code blocks will end up being escaped like below [Example 0], also a PR #367 was created, could you please help see if it's the way to fix this(sorry, I didn't try it via mkdocs yet)?

2. 检查主机上的GCC和CMake版本是否正确。版本信息请参见[软件要求](#_4)。
```bash
$ g++ --version
$ cmake --version
```
如果版本正确，您可以跳过本小节。如果不正确，请根据如下步骤安装：
1. 克隆仓库`nebula-common`到主机。
```bash
$ git clone https://github.com/vesoft-inc/nebula-common.git
```
类似{{ nebula.release }}版本的Nebula Graph源码存储在特定的分支，您可以使用`--branch`或`-b`选项指定克隆的分支。例如指定{{ nebula.release }}，命令如下：
```bash
$ git clone --branch v{{ nebula.release }} https://github.com/vesoft-inc/nebula-common.git
```
2. 进入目录`nebula-common`。
```bash
$ cd nebula-common
```Proposed Change would be to remove the indentation, which is not yet verified.

The command to change password in the document:
CHANGE PASSWORD
<user_name>FROM<old_psw>TO<new-psw>;
When I use then command
CHANGE PASSWORD root FROM nebula TO fjsdhGYHF@GGHF65fjkshfk;then got the tip:
SyntaxError:syntax error nearnebula'
After some attempts, I learned that the password field requires quotation marks, like this:
CHANGE PASSWORD root FROM "nebula" TO "fjsdhGYHF@GGHF65fjkshfk";Therefore, I recommend adding examples after the commands in the documentation.

示例中age错写成name了。
GO FROM "player100" OVER follow YIELD $^.player.age AS SrcAge, $$.player.age AS DestAge;rand32(5)的结果是[0, 5)输出结果可能是0，所以会出现输出为空的时候。
(root@nebula) [basketballplayer]> MATCH (v:player) RETURN v.name AS Name, v.age AS Age ORDER BY Age LIMIT rand32(5);输出为：
