Five data columns are ts (timestamp), c1 (bigint), c3 (binary), c2 (bool), c4 (bigint). The mapping becomes the following SQL statement. +This row is mapped to a supertable: `st` contains three NCHAR tags: t1, t2, and t3.

As shown below, the +If you use line protocol to write to a specific tag field and then later change the field type, a schema error will ocur. This triggers an error on the write API. This is shown as follows: ```json -st,t1=3,t2=4,t3=t3 c1=3i64,c3="passit",c2=false,c4=4 1626006833639000000 -st,t1=3,t2=4,t3=t3 c1=3i64,c3="passit",c2=false,c4=4i 1626006833640000000 +st,t1=3,t2=4,t3=t3 c1=3i64,c3="passit",c2=false,c4=4 1626006833639000000 +st,t1=3,t2=4,t3=t3 c1=3i64,c3="passit",c2=false,c4=4i 1626006833640000000 ``` -The data type mapping in the first row defines column c4 as DOUBLE, but the data in the second row is declared as BIGINT by the numeric suffix, which triggers a parsing error with schemaless writing. +The first row defines c4 as a double. However, in the second row, the suffix indicates that the value of c4 is a bigint. This causes schemaless writing to throw an error. -If the line protocol before the column declares the data column as BINARY, the subsequent one requires a longer binary length, which triggers a super table schema change. +An error also occurs if data input into a binary column exceeds the defined length of the column. ```json -st,t1=3,t2=4,t3=t3 c1=3i64,c5="pass" 1626006833639000000 -st,t1=3,t2=4,t3=t3 c1=3i64,c5="passit" 1626006833640000000 +st,t1=3,t2=4,t3=t3 c1=3i64,c5="pass" 1626006833639000000 +st,t1=3,t2=4,t3=t3 c1=3i64,c5="passit" 1626006833640000000 ``` -The first line of the line protocol parsing will declare column c5 is a BINARY(4) field. The second line data write will parse column c5 as a BINARY column. But in the second line, c5's width is 6 so you need to increase the width of the BINARY field to be able to accommodate the new string. +The first row defines c5 as a binary(4). but the second row writes 6 bytes to it. This means that the length of the binary column must be expanded to contain the data. ```json -st,t1=3,t2=4,t3=t3 c1=3i64 1626006833639000000 -st,t1=3,t2=4,t3=t3 c1=3i64,c6="passit" 1626006833640000000 +st,t1=3,t2=4,t3=t3 c1=3i64 1626006833639000000 +st,t1=3,t2=4,t3=t3 c1=3i64,c6="passit" 1626006833640000000 ``` -The second line of data has an additional column c6 of type BINARY(6) compared to the first row. Then a column c6 of type BINARY(6) is automatically added at this point. +The preceding data includes a new entry, c6, with type binary(6).

This can be configured by the parameter `maxVgroupsPerDb`. Each vnode in a vgroup stores one replica. Each vnode consumes a fixed amount of memory, i.e. `blocks` \* `cache`. In addition, some memory is required for tag values associated with each table. A fixed amount of memory is required for each cluster. So, the memory required for each DB can be calculated using the formula below: +Each database creates a fixed number of vgroups. This number is 2 by default and can be configured with the `vgroups` parameter. The number of replicas can be controlled with the `replica` parameter. Each replica requires one vnode per vgroup. Altogether, the memory required by each database depends on the following configuration options: + +- vgroups +- replica +- buffer +- pages +- pagesize +- cachesize + +For more information, see [Database](../../taos-sql/database). + +The memory required by a database is therefore greater than or equal to: ``` -Database Memory Size = maxVgroupsPerDb * replica * (blocks * cache + 10MB) + numOfTables * (tagSizePerTable + 0.5KB) +vgroups * replica * (buffer + pages * pagesize + cachesize) ``` -For example, assuming the default value of `maxVgroupPerDB` is 64, the default value of `cache` is 16M, the default value of `blocks` is 6, there are 100,000 tables in a DB, the replica number is 1, total length of tag values is 256 bytes, the total memory required for this DB is: 64 \* 1 \* (16 \* 6 + 10) + 100000 \* (0.25 + 0.5) / 1000 = 6792M. +However, note that this requirement is spread over all dnodes in the cluster, not on a single physical machine. The physical servers that run dnodes meet the requirement together. If a cluster has multiple databases, the memory required increases accordingly. In complex environments where dnodes were added after initial deployment in response to increasing resource requirements, load may not be balanced among the original dnodes and newer dnodes. In this situation, the actual status of your dnodes is more important than theoretical calculations. -In the real operation of TDengine, we are more concerned about the memory used by each TDengine server process `taosd`. - -``` - taosd_memory = vnode_memory + mnode_memory + query_memory -``` - -In the above formula: - -1.

Parameters can be used when testing network speed are as below: - --n：When set to "speed", it means testing network speed. --h：The FQDN or IP of the server process to be connected to; if not set, the FQDN configured in `taos.cfg` is used. --P：The port of the server process to connect to, the default value is 6030. --N：The number of packages that will be sent in the test, range is [1,10000], default value is 100. --l：The size of each package in bytes, range is [1024, 1024 \* 1024 \* 1024], default value is 1024. --S：The type of network packages to send, can be either TCP or UDP, default value is TCP. - -## FQDN Resolution Diagnostic - -`taos -n fqdn -h ` - -From version 2.2.0.0 onward, the above command can be executed in a Linux shell to test the resolution speed of FQDN.

The parameters that can be used for this purpose are as below: - --n：When set to "fqdn", it means testing the speed of resolving FQDN. --h：The FQDN to be resolved. If not set, the `FQDN` parameter in `taos.cfg` is used by default. - ## Server Log -The parameter `debugFlag` is used to control the log level of the `taosd` server process. The default value is 131.

help much, please submit an issue on [GitHub](https://github.com/taosdata/TDengine) to describe your problem. In your description please include the TDengine version, hardware and OS information, the steps to reproduce the problem and any other relevant information. It would be very helpful if you can package the contents in `/var/log/taos` and `/etc/taos` and upload. These two are the default directories used by TDengine. If you have changed the default directories in your configuration, please package the files in your configured directories. We recommended setting `debugFlag` to 135 in `taos.cfg`, restarting `taosd`, then reproducing the problem and collecting the logs. If you don't want to restart, an alternative way of setting `debugFlag` is executing `alter dnode debugFlag 135` command in TDengine CLI `taos`. During normal running, however, please make sure `debugFlag` is set to 131. +If your issue could not be resolved by reviewing this documentation, you can submit your issue on GitHub and receive support from the TDengine Team. When you submit an issue, attach the following directories from your TDengine deployment: + +1. The directory containing TDengine logs (`/var/log/taos` by default) +2. The directory containing TDengine configuration files (`/etc/taos` by default) + +In your GitHub issue, provide the version of TDengine and the operating system and environment for your deployment, the operations that you performed when the issue occurred, and the time of occurrence and affected tables. + +To obtain more debugging information, open `taos.cfg` and set the `debugFlag` parameter to `135`. Then restart TDengine Server and reproduce the issue. The debug-level logs generated help the TDengine Team to resolve your issue. If it is not possible to restart TDengine Server, you can run the following command in the TDengine CLI to set the debug flag: + +``` + alter dnode 'debugFlag' '135'; +``` + +You can run the `SHOW DNODES` command to determine the dnode ID. + +When debugging information is no longer needed, set `debugFlag` to 131. ## Frequently Asked Questions -### 1. How to upgrade to TDengine 2.0 from older version? +### 1. What are the best practices for upgrading a previous version of TDengine to version 3.0? -version 2.x is not compatible with version 1.x. With regard to the configuration and data files, please perform the following steps before upgrading. Please follow data integrity, security, backup and other relevant SOPs, best practices before removing/deleting any data. +TDengine 3.0 is not compatible with the configuration and data files from previous versions.

How can I resolve the "Unable to establish connection" error? -When the client is unable to connect to the server, you can try the following ways to troubleshoot and resolve the problem. +This error indicates that the client could not connect to the server. Perform the following troubleshooting steps: -1. Check the network +1. Check the network. - - Check if the hosts where the client and server are running are accessible to each other, for example by `ping` command. - - Check if the TCP/UDP on port 6030-6042 are open for access if firewall is enabled. If possible, disable the firewall for diagnostics, but please ensure that you are following security and other relevant protocols. - - Check if the FQDN and serverPort are configured correctly in `taos.cfg` used by the server side. - - Check if the `firstEp` is set properly in the `taos.cfg` used by the client side. + - For machines deployed in the cloud, verify that your security group can access ports 6030 and 6031 (TCP and UDP). + - For virtual machines deployed locally, verify that the hosts where the client and server are running are accessible to each other. Do not use localhost as the hostname. + - For machines deployed on a corporate network, verify that your NAT configuration allows the server to respond to the client. -2. Make sure the client version and server version are same. +2. Verify that the client and server are running the same version of TDengine. -3. On server side, check the running status of `taosd` by executing `systemctl status taosd` . If your server is started using another way instead of `systemctl`, use the proper method to check whether the server process is running normally. +3. On the server, run `systemctl status taosd` to verify that taosd is running normally. If taosd is stopped, run `systemctl start taosd`. -4. If using connector of Python, Java, Go, Rust, C#, node.JS on Linux to connect to the server, please make sure `libtaos.so` is in directory `/usr/local/taos/driver` and `/usr/local/taos/driver` is in system lib search environment variable `LD_LIBRARY_PATH`. +4. Verify that the client is configured with the correct FQDN for the server. -5. If using connector on Windows, please make sure `C:\TDengine\driver\taos.dll` is in your system lib search path. We recommend putting `taos.dll` under `C:\Windows\System32`. +5. If the server cannot be reached with the `ping` command, verify that network and DNS or hosts file settings are correct. For a TDengine cluster, the client must be able to ping the FQDN of every node in the cluster. -6. Some advanced network diagnostics tools +6. Verify that your firewall settings allow all hosts in the cluster to communicate on ports 6030 and 6041 (TCP and UDP). You can run `ufw status` (Ubuntu) or `firewall-cmd --list-port` (CentOS) to check the configuration. - - On Linux system tool `nc` can be used to check whether the TCP/UDP can be accessible on a specified port - Check whether a UDP port is open: `nc -vuz {hostIP} {port} ` - Check whether a TCP port on server side is open: `nc -l {port}` - Check whether a TCP port on client side is open: `nc {hostIP} {port}` +7. If you are using the Python, Java, Go, Rust, C#, or Node.js connector on Linux to connect to the server, verify that `libtaos.so` is in the `/usr/local/taos/driver` directory and `/usr/local/taos/driver` is in the `LD_LIBRARY_PATH` environment variable. - - On Windows system `Test-NetConnection -ComputerName {fqdn} -Port {port}` on PowerShell can be used to check whether the port on server side is open for access. +8. If you are using Windows, verify that `C:\TDengine\driver\taos.dll` is in the `PATH` environment variable. If possible, move `taos.dll` to the `C:\Windows\System32` directory. -7. TDengine CLI `taos` can also be used to check network, please refer to [TDengine CLI](/reference/taos-shell). +9. On Linux systems, you can use the `nc` tool to check whether a port is accessible: + - To check whether a UDP port is open, run `nc -vuz {hostIP} {port}`. + - To check whether a TCP port on the server side is open, run `nc -l {port}`. + - To check whether a TCP port on client side is open, run `nc {hostIP} {port}`. -### 3. How to handle "Unexpected generic error in RPC" or "Unable to resolve FQDN" ? +10. On Windows systems, you can run `Test-NetConnection -ComputerName {fqdn} -Port {port}` in PowerShell to check whether a port on the server side is accessible. -This error is caused because the FQDN can't be resolved. Please try following ways: +11. You can also use the TDengine CLI to diagnose network issues. For more information, see [Problem Diagnostics](https://docs.tdengine.com/operation/diagnose/). -1. Check whether the FQDN is configured properly on the server side -2. If DSN server is configured in the network, please check whether it works; otherwise, check `/etc/hosts` to see whether the FQDN is configured with correct IP -3. If the network configuration on the server side is OK, try to ping the server from the client side. -4. If TDengine has been used before with an old hostname then the hostname has been changed, please check `/var/lib/taos/taos/dnode/dnodeEps.json`. Before setting up a new TDengine cluster, it's better to cleanup the directories configured. +### 5. How can I resolve the "Unable to resolve FQDN" error? -### 4. "Invalid SQL" is returned even though the Syntax is correct +Clients and dnodes must be able to resolve the FQDN of each required node. You can confirm your configuration as follows: -"Invalid SQL" is returned when the length of SQL statement exceeds maximum allowed length or the syntax is not correct. +1. Verify that the FQDN is configured properly on the server. +2. If your network has a DNS server, verify that it is operational. +3. If your network does not have a DNS server, verify that the FQDNs in the `hosts` file are correct. +4. On the client, use the `ping` command to test your connection to the server. If you cannot ping an FQDN, TDengine cannot reach it. +5. If TDengine has been previously installed and the `hostname` was modified, open `dnode.json` in the `data` folder and verify that the endpoint configuration is correct. The default location of the dnode file is `/var/lib/taos/dnode`. Ensure that you clean up previous installations before reinstalling TDengine. +6. Confirm whether FQDNs are preconfigured in `/etc/hosts` and `/etc/hostname`. -### 5. Whether validation queries are supported? +### 6. What is the most effective way to write data to TDengine? -It's suggested to use a builtin database named as `log` to monitor. +Writing data in batches provides higher efficiency in most situations. You can insert one or more data records into one or more tables in a single SQL statement. - +### 9. Why are table names not fully displayed? -### 6. Can I delete a record? +The number of columns in the TDengine CLI terminal display is limited. This can cause table names to be cut off, and if you use an incomplete name in a statement, the "Table does not exist" error will occur. You can increase the display size with the `maxBinaryDisplayWidth` parameter or the SQL statement `set max_binary_display_width`. You can also append `\G` to your SQL statement to bypass this limitation. -From version 2.6.0.0 Enterprise version, deleting data can be supported. +### 10. How can I migrate data? -### 7. How to create a table of over 1024 columns? +In TDengine, the `hostname` uniquely identifies a machine. When you move data files to a new machine, you must configure the new machine to have the same `host name` as the original machine. -From version 2.1.7.0, at most 4096 columns can be defined for a table. +:::note -### 8. How to improve the efficiency of inserting data? +The data structure of previous versions of TDengine is not compatible with version 3.0. To migrate from TDengine 1.x or 2.x to 3.0, you must export data from your older deployment and import it back into TDengine 3.0. -Inserting data in batch is a good practice. Single SQL statement can insert data for one or multiple tables in batch. +::: -### 9. JDBC Error： the executed SQL is not a DML or a DDL？ +### 11. How can I temporary change the log level from the TDengine Client? -Please upgrade to latest JDBC driver, for details please refer to [Java Connector](/reference/connector/java) - -### 10. Failed to connect with error "invalid timestamp" - -The most common reason is that the time setting is not aligned on the client side and the server side. On Linux system, please use `ntpdate` command. On Windows system, please enable automatic sync in system time setting. - -### 11. Table name is not shown in full - -There is a display width setting in TDengine CLI `taos`. It can be controlled by configuration parameter `maxBinaryDisplayWidth`, or can be set using SQL command `set max_binary_display_width`. A more convenient way is to append `\G` in a SQL command to bypass this limitation. - -### 12. How to change log level temporarily? - -Below SQL command can be used to adjust log level temporarily +To change the log level for debugging purposes, you can use the following command: ```sql -ALTER LOCAL flag_name flag_value; +ALTER LOCAL local_option + +local_option: { + 'resetLog' + | 'rpcDebugFlag' value + | 'tmrDebugFlag' value + | 'cDebugFlag' value + | 'uDebugFlag' value + | 'debugFlag' value +} ``` - - flag_name can be: debugFlag，cDebugFlag，tmrDebugFlag，uDebugFlag，rpcDebugFlag - - flag_value can be: 131 (INFO/WARNING/ERROR), 135 (plus DEBUG), 143 (plus TRACE) - +Use `resetlog` to remove all logs generated on the local client. Use the other parameters to specify a log level for a specific component. -### 13. What to do if go compilation fails? +For each parameter, you can set the value to `131` (error and warning), `135` (error, warning, and debug), or `143` (error, warning, debug, and trace). -From version 2.3.0.0, a new component named `taosAdapter` is introduced. Its' developed in Go. If you want to compile from source code and meet go compilation problems, try to do below steps to resolve Go environment problems. +### Why do TDengine components written in Go fail to compile? -```sh -go env -w GO111MODULE=on -go env -w GOPROXY=https://goproxy.cn,direct -``` +TDengine includes taosAdapter, an independent component written in Go. This component provides the REST API as well as data access for other products such as Prometheus and Telegraf. +When using the develop branch, you must run `git submodule update --init --recursive` to download the taosAdapter repository and then compile it. + +TDengine Go components require Go version 1.14 or later. + +### 13. How can I query the storage space being used by my data? + +The TDengine data files are stored in `/var/lib/taos` by default. Log files are stored in `/var/log/taos`. + +To see how much space your data files occupy, run `du -sh /var/lib/taos/vnode --exclude='wal'`. This excludes the write-ahead log (WAL) because its size is relatively fixed while writes are occurring, and it is written to disk and cleared when you shut down TDengine. + +If you want to see how much space is occupied by a single database, first determine which vgroup is storing the database by running `show vgroups`. Then check `/var/lib/taos/vnode` for the files associated with the vgroup ID. + +### 15. How is timezone information processed for timestamps? + +TDengine uses the timezone of the client for timestamps. The server timezone does not affect timestamps. The client converts Unix timestamps in SQL statements to UTC before sending them to the server. When you query data on the server, it provides timestamps in UTC to the client, which converts them to its local time. + +Timestamps are processed as follows: + +1. The client uses its system timezone unless it has been configured otherwise. +2. A timezone configured in `taos.cfg` takes precedence over the system timezone. +3. A timezone explicitly specified when establishing a connection to TDengine through a connector takes precedence over `taos.cfg` and the system timezone. For example, the Java connector allows you to specify a timezone in the JDBC URL. +4. If you use an RFC 3339 timestamp (2013-04-12T15:52:01.123+08:00), or an ISO 8601 timestamp (2013-04-12T15:52:01.123+0800), the timezone specified in the timestamp is used instead of the timestamps configured using any other method. + +### 16. Which network ports are required by TDengine? + +See [serverPort](https://docs.tdengine.com/reference/config/#serverport) in Configuration Parameters. + +Note that ports are specified using 6030 as the default first port. If you change this port, all other ports change as well. + +### 17. Why do applications such as Grafana fail to connect to TDengine over the REST API? + +In TDengine, the REST API is provided by taosAdapter. Ensure that taosAdapter is running before you connect an application to TDengine over the REST API. You can run `systemctl start taosadapter` to start the service. + +Note that the log path for taosAdapter must be configured separately. The default path is `/var/log/taos`. You can choose one of eight log levels. The default is `info`. You can set the log level to `panic` to disable log output. You can modify the taosAdapter configuration file to change these settings. The default location is `/etc/taos/taosadapter.toml`. + +For more information, see [taosAdapter](https://docs.tdengine.com/reference/taosadapter/). + +### 18. How can I resolve out-of-memory (OOM) errors? + +OOM errors are thrown by the operating system when its memory, including swap, becomes insufficient and it needs to terminate processes to remain operational. Most OOM errors in TDengine occur for one of the following reasons: free memory is less than the value of `vm.min_free_kbytes` or free memory is less than the size of the request. If TDengine occupies reserved memory, an OOM error can occur even when free memory is sufficient. + +TDengine preallocates memory to each vnode. The number of vnodes per database is determined by the `vgroups` parameter, and the amount of memory per vnode is determined by the `buffer` parameter. To prevent OOM errors from occurring, ensure that you prepare sufficient memory on your hosts to support the number of vnodes that your deployment requires. Configure an appropriately sized swap space. If you continue to receive OOM errors, your SQL statements may be querying too much data for your system. TDengine Enterprise Edition includes optimized memory management that increases stability for enterprise customers.
