}nullThe API resets all existing data and then imports the new data into the system by default. But user can specify partial=1 parameter in HTTP URL to keep the existing data and apply the new data.
The API supports specifying data by means of text content or file URIs.
Example 1: Import by text content
POST http://{{host}}/data/import
Content-Type: application/json
{
"content": "{json of the ruleset}"
}
Example 2: Import by file URI
POST http://{{host}}/data/import
Content-Type: application/json
{
"file": "file:///tmp/a.json"
}
Example 3: Import data via file URI and exit (for plug-ins and static schema updates, users need to ensure that eKuiper can be restarted after exiting)
POST http://{{host}}/data/import?stop=1
Content-Type: application/json
{
"file": "file:///tmp/a.json"
}
Example 4: Keep the old data and import new data (overwrite the tables/streams/rules/source config/sink config. install plugins/schema if not exist, else ignore them)
POST http://{{host}}/data/import?partial=1
Content-Type: application/json
{
"file": "file:///tmp/a.json"
}
The file format for importing and exporting data is JSON, which can contain : streams, tables, rules, plugin, source yaml and so on. Each type holds the the key-value pair of the name and the creation statement. In the following example file, we define stream 、rules、table、plugin、source config、sink config

}The API accepts a JSON content to create a new plugin.The plugin is identified by the name. The name must be unique.
Random, then the name of this plugin is random.http or https scheme or file scheme to refer to a local file path of the eKuiper server. It must be a zip file with: a compiled so file and the yaml file(only required for sources). If the plugin depends on some external dependencies, a bash script named install.sh can be provided to do the dependency installation. The name of the files must match the name of the plugin.A sample zip file for a source named random.zip
Notice that, the install.sh will be run that the system may already had the lib or package. Make sure to check the path before. Below is an example install.sh to install a sample sdk lib.

}The API is used for drop the plugin. Notice that, for native plugins, the eKuiper server needs to be restarted to take effect. The current rules will continue to run with the deleted native plugins successfully. For portable plugin, the deletion will take effect immediately. The current rules which are using that plugin may encounter errors but won't stop and can continue running if an updated plugin with the same name is created later. If this is not expected, manually stop or delete those rules before deleting a plugin.
The user can pass a query parameter to decide if eKuiper should be stopped after a delete in order to make the deletion take effect. The parameter is stop and only when the value is 1 will the eKuiper be stopped. The user has to manually restart it.

{ }Notice that, native plugins can be updated, but the new version will not take effect until the eKuiper server is restarted. Portable plugins can be updated, and the new version will take effect immediately even for the running rules. The request body is the same as the create plugin request.

{ }The API is used for displaying all user defined functions which are defined across all plugins.
Unlike source and sink plugins, function plugin can export multiple functions at once. The exported names must be unique globally across all plugins. There will be a one to many mapping between function and its container plugin. Thus, we provide show udf(user defined function) api to query all user defined functions so that users can check the name duplication. And we provide describe udf api to find out the defined plugin of a function. We also provide the register functions api to register the udf list for an auto loaded plugin.

}The API aims to register all exported functions in an auto loaded function plugin or when the exported functions are changed. If the plugin was loaded by CLI create command or REST create API with functions property specified, then this is not needed. The register API will persist the functions list in the kv. Unless the exported functions are changed, users only need to register it once. APIs to handle function plugin with multiple functions

The file format for importing and exporting ruleset is JSON, which can contain three parts: streams, tables and rules. Each type holds the the key-value pair of the name and the creation statement. In the following example file, we define a stream and two rules.

}The API is used for update the table definition.
| id required | string the id or name of the old table. |
{- "sql": "create table my_table (id bigint, name string, score float) WITH ( datasource = \"topic/temperature\", FORMAT = \"json\", KEY = \"id\")"
}The API supports to upload a local file, provide the text content of file or upload a http file link. The upload request will save the file into your ${dataPath}/uploads. It will override the existed file of the same name. The response is the absolute path of the uploaded file which you can refer in other configurations.
The API accepts a multipart file upload requests. Below is an example html file to upload file to http://127.0.0.1:9081/config/uploads. In the form data, the file input name must be uploadFile.
<html lang="en">

Create a trial run rule, wait for it to run. This API can check syntax, ensuring the creation of an executable trial run rule.After the rule is created successfully, the websocket endpoint starts. Users can listen to the websocket address http://locahost:10081/test/uuid to get the result output. Among them, the port and id are the above return values.
| id required | string or null The id of the test rule, required, used for subsequent test rule management. Ensure uniqueness, it cannot be repeated with other test rules, otherwise the original test rule will be overwritten. This id has no association with the id of ordinary rules. |
| sql required | string or null The sql statement of the test rule, required, used to define the syntax of the test rule. |
required | object or null The mock rule definition of the data source of the test rule, optional, used to define the input data of the test rule. If not defined, the real data source in SQL will be used. |
required | object or null The definition of the sink parameters of the test rule, optional. Most of the common parameters of the sink can be used, such as dataTemplate and fields. If not defined, the default sink parameters will be used. |

}Besides defining function in plugins, user-defined functions (UDF) are also supported independently. Currently, we only support JavaScript UDF. We can use REST API or CLI to manage JavaScript functions.
Use this endpoint to create a new function.
| id required | string A unique name for the function. This name must also be defined as a function in the script field. |
| description required | string A brief description of the function. |
| script required | string The function implementation in JavaScript. |
| isAgg required | boolean A boolean indicating whether the function is an aggregate function. |
{- "id": "area",
- "description": "calculate area",
- "script": "function area(x, y) { return x * y; }",
- "isAgg": false
}{ }Use this endpoint to get the detailed definition of a function.Replace {id} with the name of the function you want to describe. The response will be a JSON object with the function's details.
| id required | string |
{- "id": "area",
- "description": "calculate area",
- "script": "function area(x, y) { return x * y; }",
- "isAgg": false
}Use this endpoint to delete a function.Replace {id} with the name of the function you want to delete. Note that you need to manually stop or delete any rules using the UDF before deleting it. A running rule will not be affected by the deletion of a UDF.
| id required | string |
{ }The JavaScript UDF can be updated and hot reload. Notice that, a running rule must be restarted to load the updated function.Replace {id} with the name of the function you want to update. The request body should be the same as when creating a UDF. If the function of the id does not exist, it will be created. Otherwise, it will be updated.
