 使用 TDengine 来搭建一个物联网大数据平台，计算资源、存储资源需要根据业务场景进行规划。下面分别讨论系统运行所需要的内存、CPU 以及硬盘空间。
 
-## 内存需求
+## 服务端内存需求
 
-每个 Database 可以创建固定数目的 vgroup，默认与 CPU 核数相同，可通过 maxVgroupsPerDb 配置；vgroup 中的每个副本会是一个 vnode；每个 vnode 会占用固定大小的内存（大小与数据库的配置参数 blocks 和 cache 有关)；每个 Table 会占用与标签总长度有关的内存；此外，系统会有一些固定的内存开销。因此，每个 DB 需要的系统内存可通过如下公式计算：
+每个 Database 可以创建固定数目的 vgroup，默认 2 个 vgroup，在创建数据库时可以通过`vgroups <num>`参数来指定，其副本数由参数`replica <num>`指定。vgroup 中的每个副本会是一个 vnode；所以每个数据库占用的内存由以下几个参数决定：
 
-```
-Database Memory Size = maxVgroupsPerDb * replica * (blocks * cache + 10MB) + numOfTables * (tagSizePerTable + 0.5KB)
-```
+- vgroups
+- replica
+- buffer
+- pages
+- pagesize
+- cachesize
 
-示例：假设 maxVgroupPerDB 是缺省值 64，cache 是缺省大小 16M, blocks 是缺省值 6，并且一个 DB 中有 10 万张表，单副本，标签总长度是 256 字节，则这个 DB 总的内存需求为：64 \* 1 \* (16 \* 6 + 10) + 100000 \* (0.25 + 0.5) / 1000 = 6792M。
+关于这些参数的详细说明请参考 [数据库管理](../../taos-sql/database)。
 
-在实际的系统运维中，我们通常会更关心 TDengine 服务进程（taosd）会占用的内存量。
+一个数据库所需要的内存大小等于
 
 ```
-taosd 内存总量 = vnode 内存 + mnode 内存 + 查询内存
+vgroups * replica * (buffer + pages * pagesize + cachesize)
 ```
 
-其中：
-
-1. “vnode 内存”指的是集群中所有的 Database 存储分摊到当前 taosd 节点上所占用的内存资源。可以按上文“Database Memory Size”计算公式估算每个 DB 的内存占用量进行加总，再按集群中总共的 TDengine 节点数做平均（如果设置为多副本，则还需要乘以对应的副本倍数）。
-2. “mnode 内存”指的是集群中管理节点所占用的资源。如果一个 taosd 节点上分布有 mnode 管理节点，则内存消耗还需要增加“0.2KB \* 集群中数据表总数”。
-3. “查询内存”指的是服务端处理查询请求时所需要占用的内存。单条查询语句至少会占用“0.2KB \* 查询涉及的数据表总数”的内存量。
+但要注意的是这些内存并不需要由单一服务器提供，而是由整个集群中所有数据节点共同负担，相当于由这些数据节点所在的服务器共同负担。如果集群中有不止一个数据库，则所需内存要累加。更复杂的场景是如果集群中的数据节点并非在最初就一次性全部建立，而是随着使用中系统负载的增加逐步增加服务器并增加数据节点，则新创建的数据库会导致新旧数据节点上的负载并不均衡，此时简单的理论计算并不能直接使用，要结合各数据节点的负载情况。
 
-注意：以上内存估算方法，主要讲解了系统的“必须内存需求”，而不是“内存总数上限”。在实际运行的生产环境中，由于操作系统缓存、资源管理调度等方面的原因，内存规划应当在估算结果的基础上保留一定冗余，以维持系统状态和系统性能的稳定性。并且，生产环境通常会配置系统资源的监控工具，以便及时发现硬件资源的紧缺情况。
-
-最后，如果内存充裕，可以考虑加大 Blocks 的配置，这样更多数据将保存在内存里，提高写入和查询速度。

 - **数据插入** TDengine 单核每秒能至少处理一万个插入请求。每个插入请求可以带多条记录，一次插入一条记录与插入 10 条记录，消耗的计算资源差别很小。因此每次插入，条数越大，插入效率越高。如果一个插入请求带 200 条以上记录，单核就能达到每秒插入 100 万条记录的速度。但对前端数据采集的要求越高，因为需要缓存记录，然后一批插入。
 - **查询需求** TDengine 提供高效的查询，但是每个场景的查询差异很大，查询频次变化也很大，难以给出客观数字。需要用户针对自己的场景，写一些查询语句，才能确定。
 
-因此仅对数据插入而言，CPU 是可以估算出来的，但查询所耗的计算资源无法估算。在实际运营过程中，不建议 CPU 使用率超过 50%，超过后，需要增加新的节点，以获得更多计算资源。

+TDengine 支持 **WAL**（Write Ahead Log）机制，实现数据的容错能力，保证数据的高可用。
 
 TDengine 接收到应用的请求数据包时，先将请求的原始数据包写入数据库日志文件，等数据成功写入数据库数据文件后，再删除相应的 WAL。这样保证了 TDengine 能够在断电等因素导致的服务重启时从数据库日志文件中恢复数据，避免数据的丢失。
 
 涉及的系统配置参数有两个：
 
-- walLevel：WAL 级别，0：不写 WAL; 1：写 WAL, 但不执行 fsync; 2：写 WAL, 而且执行 fsync。
-- fsync：当 walLevel 设置为 2 时，执行 fsync 的周期。设置为 0，表示每次写入，立即执行 fsync。

+- wal_fsync_period：当 wal_level 设置为 2 时，执行 fsync 的周期。设置为 0，表示每次写入，立即执行 fsync。
 
-如果要 100%的保证数据不丢失，需要将 walLevel 设置为 2，fsync 设置为 0。这时写入速度将会下降。但如果应用侧启动的写数据的线程数达到一定的数量(超过 50)，那么写入数据的性能也会很不错，只会比 fsync 设置为 3000 毫秒下降 30%左右。
