 DolphinScheduler is a distributed and extensible workflow scheduler platform with powerful DAG visual interfaces, dedicated to solving complex job dependencies in the data pipeline and providing various types of jobs available `out of the box`.
 
-Its main objectives are as follows:
- -  Highly Reliable,
-DolphinScheduler adopts a decentralized multi-master and multi-worker architecture design, which naturally supports easy expansion and high availability (not restricted by a single point of bottleneck), and its performance increases linearly with the increase of machines
- - High performance, supporting tens of millions of tasks every day
- - Support multi-tenant.
- - Cloud Native, DolphinScheduler supports multi-cloud/data center workflow management, also
-supports Kubernetes, Docker deployment and custom task types, distributed
-scheduling, with overall scheduling capability increased linearly with the
-scale of the cluster
- - Support various task types: Shell, MR, Spark, SQL (MySQL, PostgreSQL, hive, spark SQL), Python, Sub_Process, Procedure, etc.
- - Support scheduling of workflows and dependencies, manual scheduling to pause/stop/recover task, support failure task retry/alarm, recover specified nodes from failure, kill task, etc.
- - Associate the tasks according to the dependencies of the tasks in a DAG graph, which can visualize the running state of the task in real-time.
- - WYSIWYG online editing tasks
- - Support the priority of workflows & tasks, task failover, and task timeout alarm or failure.
- - Support workflow global parameters and node customized parameter settings.
- - Support online upload/download/management of resource files, etc. Support online file creation and editing.
- - Support task log online viewing and scrolling and downloading, etc.
- - Support the viewing of Master/Worker CPU load, memory, and CPU usage metrics.
- - Support displaying workflow history in tree/Gantt chart, as well as statistical analysis on the task status & process status in each workflow.
- - Support back-filling data.
- - Support internationalization.
- - More features waiting for partners to explore...
+The key features for DolphinScheduler are as follows:
+- Easy to deploy, we provide 4 ways to deploy, such as Standalone deployment,Cluster deployment,Docker / Kubernetes deployment and Rainbond deployment
+- Easy to use, there are four ways to create workflows:
+  - Visually, create tasks by dragging and dropping tasks
+  - [PyDolphinScheduler](https://dolphinscheduler.apache.org/python/main/index.html), Creating workflows via Python API, aka workflow-as-code
+  - Yaml definition, mapping yaml into workflow(have to install PyDolphinScheduler currently)
+  - Open API, Creating workflows
 
-## What's in DolphinScheduler
+- Highly Reliable,
+DolphinScheduler uses a decentralized multi-master and multi-worker architecture, which naturally supports horizontal scaling and high availability
+- High performance, its performance is N times faster than other orchestration platform and it can support tens of millions of tasks per day
+- Supports multi-tenancy
+- Supports various task types: Shell, MR, Spark, SQL (MySQL, PostgreSQL, Hive, Spark SQL), Python, Procedure, Sub_Workflow,
+Http, K8s, Jupyter, MLflow, SageMaker, DVC, Pytorch, Amazon EMR, etc
+- Orchestrating workflows and dependencies, you can pause/stop/recover task any time, failed tasks can be set to automatically retry
+- Visualizing the running state of the task in real-time and seeing the task runtime log
+- What you see is what you get when you edit the task on the UI
+- Backfill can be operated on the UI directly
+- Perfect project, resource, data source-level permission control
+- Displaying workflow history in tree/Gantt chart, as well as statistical analysis on the task status & process status in each workflow
+- Supports internationalization
+- Cloud Native, DolphinScheduler supports orchestrating multi-cloud/data center workflow, and 
+supports custom task type
+- More features waiting for partners to explore
 
- Stability | Accessibility | Features | Scalability |
- --------- | ------------- | -------- | ------------|
-Decentralized multi-master and multi-worker | Visualization of workflow key information, such as task status, task type, retry times, task operation machine information, visual variables, and so on at a glance.  |  Support pause, recover operation | Support customized task types
-support HA | Visualization of all workflow operations, dragging tasks to draw DAGs, configuring data sources and resources. At the same time, for third-party systems, provide API mode operations. | Users on DolphinScheduler can achieve many-to-one or one-to-one mapping relationship through tenants and Hadoop users, which is very important for scheduling large data jobs.  | The scheduler supports distributed scheduling, and the overall scheduling capability will increase linearly with the scale of the cluster. Master and Worker support dynamic adjustment.

 - A process definition corresponds to multiple task definitions, which are associated through `t_ds_process_task_relation` and the associated key is `code + version`. When the pre-task of the task is empty, the corresponding `pre_task_node` and `pre_task_version` are 0.
 - A process definition can have multiple process instances `t_ds_process_instance`, one process instance corresponds to one or more task instances `t_ds_task_instance`.
 - The data stored in the `t_ds_relation_process_instance` table is used to handle the case that the process definition contains sub-processes. `parent_process_instance_id` represents the id of the main process instance containing the sub-process, `process_instance_id` represents the id of the sub-process instance, `parent_task_instance_id` represents the task instance id of the sub-process node. The process instance table and the task instance table correspond to the `t_ds_process_instance` table and the `t_ds_task_instance` table, respectively.

 # API design standard
+
 A standardized and unified API is the cornerstone of project design.The API of DolphinScheduler follows the REST ful standard. REST ful is currently the most popular Internet software architecture. It has a clear structure, conforms to standards, is easy to understand and extend.
 
 This article uses the DolphinScheduler API as an example to explain how to construct a Restful API.
 
 ## 1. URI design
+
 REST is "Representational State Transfer".The design of Restful URI is based on resources.The resource corresponds to an entity on the network, for example: a piece of text, a picture, and a service. And each resource corresponds to a URI.
 
 + One Kind of Resource: expressed in the plural, such as `task-instances`、`groups` ;
@@ -12,36 +14,43 @@ REST is "Representational State Transfer".The design of Restful URI is based on
 + A Sub Resource：`/instances/{instanceId}/tasks/{taskId}`;
 
 ## 2. Method design
+
 We need to locate a certain resource by URI, and then use Method or declare actions in the path suffix to reflect the operation of the resource.
 
 ### ① Query - GET
+
 Use URI to locate the resource, and use GET to indicate query.
 
 + When the URI is a type of resource, it means to query a type of resource. For example, the following example indicates paging query `alter-groups`.
+
 ```
 Method: GET
 /dolphinscheduler/alert-groups
 ```
 
 + When the URI is a single resource, it means to query this resource. For example, the following example means to query the specified `alter-group`.
+
 ```
 Method: GET
 /dolphinscheduler/alter-groups/{id}
 ```
 
 + In addition, we can also express query sub-resources based on URI, as follows:
+
 ```
 Method: GET
 /dolphinscheduler/projects/{projectId}/tasks
 ```
 
 **The above examples all represent paging query. If we need to query all data, we need to add `/list` after the URI to distinguish. Do not mix the same API for both paged query and query.**
+
 ```
 Method: GET
 /dolphinscheduler/alert-groups/list
 ```

 - In the decentralized design, there is usually no Master/Slave concept, all roles are the same, the status is equal, the global Internet is a typical decentralized distributed system, networked arbitrary node equipment down machine , all will only affect a small range of features.
 - The core design of decentralized design is that there is no "manager" that is different from other nodes in the entire distributed system, so there is no single point of failure problem. However, since there is no "manager" node, each node needs to communicate with other nodes to get the necessary machine information, and the unreliable line of distributed system communication greatly increases the difficulty of implementing the above functions.
 - In fact, truly decentralized distributed systems are rare. Instead, dynamic centralized distributed systems are constantly emerging. Under this architecture, the managers in the cluster are dynamically selected, rather than preset, and when the cluster fails, the nodes of the cluster will spontaneously hold "meetings" to elect new "managers". Go to preside over the work. The most typical case is the Etcd implemented in ZooKeeper and Go.
-
 - Decentralization of DolphinScheduler is the registration of Master/Worker to ZooKeeper. The Master Cluster and the Worker Cluster are not centered, and the Zookeeper distributed lock is used to elect one Master or Worker as the “manager” to perform the task.

 ##### V. Task priority design
 
 In the early scheduling design, if there is no priority design and fair scheduling design, it will encounter the situation that the task submitted first may be completed simultaneously with the task submitted subsequently, but the priority of the process or task cannot be set. We have redesigned this, and we are currently designing it as follows:
 
 - According to **different process instance priority** prioritizes **same process instance priority** prioritizes **task priority within the same process** takes precedence over **same process** commit order from high Go to low for task processing.
-
   - The specific implementation is to resolve the priority according to the json of the task instance, and then save the **process instance priority _ process instance id_task priority _ task id** information in the ZooKeeper task queue, when obtained from the task queue, Through string comparison, you can get the task that needs to be executed first.
-
     - The priority of the process definition is that some processes need to be processed before other processes. This can be configured at the start of the process or at the time of scheduled start. There are 5 levels, followed by HIGHEST, HIGH, MEDIUM, LOW, and LOWEST. As shown below

- - Configuration Files are named in camelCase, and file names are lowercase with uppercase initial/starting letter.
- - Code that requires comment interpretation should be as small as possible and interpreted by method name.
- - `equals` and `==` In a conditional expression, the constant is left, the variable is on the right, and in the expression greater than less than condition, the variable is left and the constant is right.

- - The order in which member variables are defined and the order in which parameters are passed is consistent across classes and methods.
- - Priority is given to the use of guard statements.
- - Classes and methods have minimal access control.
- - The private method used by the method should follow the method, and if there are multiple private methods, the writing private method should appear in the same order as the private method in the original method.
- - Method entry and return values are not allowed to be `null`.
- - The return and assignment statements of if else are preferred with the tri-objective operator.
- - Priority is given to `LinkedList` and only use `ArrayList` if you need to get element values in the collection through the index.
- - Collection types such as `ArrayList`，`HashMap` that may produce expansion must specify the initial size of the collection to avoid expansion.

 # Pull Request Notice
 
 ## Preface

 Pull Request is a way of software cooperation, which is a process of bringing code involving different functions into the trunk. During this process, the code can be discussed, reviewed, and modified.
 
 In Pull Request, we try not to discuss the implementation of the code. The general implementation of the code and its logic should be determined in Issue. In the Pull Request, we only focus on the code format and code specification, so as to avoid wasting time caused by different opinions on implementation.

The contents of the logs need to be associated with the relevant information in the log format, and printing them in separate lines will cause the contents of the logs to not match the time and other information, and cause the logs to be mixed in a large number of log environments, which will make log retrieval more difficult.

 # Data Quality

 ## Introduction
 
 The data quality task is used to check the data accuracy during the integration and processing of data. Data quality tasks in this release include single-table checking, single-table custom SQL checking, multi-table accuracy, and two-table value comparisons. The running environment of the data quality task is Spark 2.4.0, and other versions have not been verified, and users can verify by themselves.
@@ -9,7 +10,7 @@ The execution logic of the data quality task is as follows:
 - When running a task, `Master` will parse `TaskParam`, encapsulate the parameters required by `DataQualityTask` and send it to `Worker`.
 - Worker runs the data quality task. After the data quality task finishes running, it writes the statistical results to the specified storage engine.
 - The current data quality task result is stored in the `t_ds_dq_execute_result` table of `dolphinscheduler`
-`Worker` sends the task result to `Master`, after `Master` receives `TaskResponse`, it will judge whether the task type is `DataQualityTask`, if so, it will read the corresponding result from `t_ds_dq_execute_result` according to `taskInstanceId`, and then The result is judged according to the check mode, operator and threshold configured by the user.

 ## Timeliness Check of Single Table Check
+
 ### Inspection Introduction
+
 The timeliness check is used to check whether the data is processed within the expected time. The start time and end time can be specified to define the time range. If the amount of data within the time range does not reach the set threshold, the check task will be judged as fail.

 ### Inspection Introduction
+
 Accuracy checks are performed by comparing the accuracy differences of data records for selected fields between two tables, examples are as follows
 - table test1
 
 | c1 | c2 |
-| :---: | :---: |
-| a | 1 |
-| b | 2 |
+|:--:|:--:|
+| a  | 1  |

 - table test2
 
 | c21 | c22 |
-| :---: | :---: |
-| a | 1 |
-| b | 3 |
+|:---:|:---:|
+|  a  |  1  |
+|  b  |  3  |
 
 If you compare the data in c1 and c21, the tables test1 and test2 are exactly the same. If you compare c2 and c22, the data in table test1 and table test2 are inconsistent.

 ## Comparison of the values checked by the two tables
+
 ### Inspection Introduction
+
 Two-table value comparison allows users to customize different SQL statistics for two tables and compare the corresponding values. For example, for the source table A, the total amount of a certain column is calculated, and for the target table, the total amount of a certain column is calculated. value sum2, compare sum1 and sum2 to determine the check result.

->If the result of the SQL node has multiple rows, one or more fields, the name of the `prop` needs to be the same as the field name. Choose the data type structure as `LIST`, and the SQL query result will be converted to `LIST<VARCHAR>`, and forward to convert to JSON as the parameter value.

 #### Save the workflow and set the global parameters
 
@@ -76,3 +81,11 @@ The result of Node_mysql is as follows:
 Even though output is assigned a value of 1 in Node_A's script, the log still shows a value of 100. But according to the principle from [parameter priority](priority.md): `Local Parameter > Parameter Context > Global Parameter`, the output value in Node_B is 1. It proves that the output parameter is passed in the workflow with reference to the expected value, and the query operation is completed using this value in Node_mysql.
 
 But the output value 66 only shows in the Node_A, the reason is that the direction of value is selected as IN, and only when the direction is OUT will it be defined as a variable output.

+#### Pass parameter from Python task to downstream
+
+Use `print('${setValue(key=%s)}' % value)`, DolphinScheduler will capture the `${setValue(key=value}` in the output to capture the parameters and pass them downstream.
