First we need to set up Temporal Server. To showcase the metrics 25 | and tracing capabilities it's easiest to use [this](https://github.com/tsurdilo/my-temporal-dockercompose) repo 26 | which has it all built in and ready to go. If you already have Temporal 27 | server running on Docker locally you can clean and prune and then run: 28 | 29 | ``` 30 | git clone https://github.com/tsurdilo/my-temporal-dockercompose 31 | cd my-temporal-dockercompose 32 | docker network create temporal-network 33 | docker compose -f docker-compose-postgres.yml -f docker-compose-services.yml up 34 | ``` 35 | 36 | 2. This demo depends on the [Temporal Spring Boot Thymeleaf UI](https://github.com/tsurdilo/temporal-springboot-web-ui) 37 | project for the web part of it. 38 | So first we have to fetch and compile it: 39 | 40 | ``` 41 | git clone git@github.com:tsurdilo/temporal-springboot-web-ui.git 42 | cd temporal-springboot-web-ui 43 | mvn clean install 44 | ``` 45 | 46 | 3. Now lets build and start the demo 47 | 48 | ``` 49 | git clone git@github.com:tsurdilo/temporal-springboot-demo.git 50 | cd temporal-springboot-demo 51 | mvn clean install spring-boot:run 52 | ``` 53 | 54 | ## Use Demo 55 | 56 | Once your demo has started up you can access the ui via 57 | [localhost:3030](http://localhost:3030/) 58 | 59 |

60 | 61 |

62 | 63 | ### Start new Execution 64 | 65 | Click on "Show/Hide" in the "Start Workflow Execution" module 66 | to expand it. This will let us start a new workflow exec. 67 | 68 |

69 | 70 |

71 | 72 | Our workflow type is "DemoWorkflow" and its running as we specified via annotations 73 | on the "DemoTaskQueue" task queue. You can set whichever workflow id you wish. 74 | The input of our workflow execution must be in CloudEvents format as 75 | that is what our custom data converter expects. 76 | Here is sample that you can use: 77 | 78 | ```json 79 | { 80 | "id": "123", 81 | "source": "localhost:3030", 82 | "type": "io.temporal.demo", 83 | "data": { 84 | "first": "john", 85 | "last": "doe" 86 | } 87 | } 88 | ``` 89 | 90 | Click on "Start Exec" to start a new workflow execution: 91 | 92 |

93 | 94 |

95 | 96 | ### Signal Execution 97 | Our execution is in "Running" status, as it is waiting on the next 98 | CloudEvent sent to it to continue. It is going to wait until we do that, 99 | so let's send it. 100 | Click on the "Signal Workflow" button in the "Actions" column: 101 | 102 | Fill in "addEvent" as the signal name, as that is what our demo workflow defines 103 | as the signal method. Enter in a different CloudEvent in the signal payload, you can use: 104 | 105 | ```json 106 | { 107 | "id": "124", 108 | "source": "localhost:3030", 109 | "type": "io.temporal.demo", 110 | "data": { 111 | "first": "marry", 112 | "last": "doe" 113 | } 114 | } 115 | ``` 116 | 117 |

118 | 119 |

120 | 121 | And click the "Signal" button. 122 | 123 | You should see that our workflow execution is now in the "Completed" status. 124 | 125 | ### Query Execution 126 | 127 | With Temporal you can query completed workflow executions (up to the 128 | configured retention period on the namespace). So let's try to query it. 129 | The query will give us the last event sent to the workflow, so we should 130 | get the same event as what we just signalled. 131 | 132 | For this click on the "Query Workflow" button in "Actions", 133 | set the query name to "getLastEvent" as that is what our workflow definition 134 | defines as the query name, then click "Query Workflow" button: 135 | 136 |

137 | 138 |

139 | 140 | ### Get Execution Result 141 | 142 | Next lets see what our workflow execution results are. Again you can get results 143 | of completed executions up to configured retention period on the namespace. 144 | 145 | For this click on the "Get Result" button in "Actions", then click on "Get Result" button. 146 | You should see the results which is also a CloudEvent that includes all the ids of the so far 147 | sent signals. For our demo that should be "123" and "124", the ids of the event 148 | that we sent as workflow data input and then the one that we signalled the workflow execution earlier: 149 | 150 |

151 | 152 |

153 | 154 | ### See Metrics and Tracing Info 155 | 156 | For metrics, in the navbar on top of the page click on "Grafana" and 157 | browse the SDK and Server dashboards that come out of the box for you. 158 | 159 | 160 | For tracing, in the navbar on top of the page click on "Jaeger". 161 | For service select "temporal-demo", and then in the Operation dropdown 162 | select "RunWorkflow:DemoWorkflow", then click "Find Traces". 163 | 164 | In the result select the http post trace which is the one the UI used 165 | to start our workflow execution: 166 | 167 |

168 | 169 |
