Getting Started#

This integration creates a workflow with a MySQL trigger and Python action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Table trigger
1. Connect your MySQL account
2. Configure timer
Configure the Run Python Code action
1. Connect your Python account
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger#

New Table on MySQL

Description:Emit new event when a new table is added to a database. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/select.html)

Version:2.0.2

MySQL Overview#

The MySQL application on Pipedream enables direct interaction with your MySQL databases, allowing you to perform CRUD operations—create, read, update, delete—on your data with ease. You can leverage these capabilities to automate data synchronization, report generation, and event-based triggers that kick off workflows in other apps. With Pipedream's serverless platform, you can connect MySQL to hundreds of other services without managing infrastructure, crafting complex code, or handling authentication.

Trigger Code#

import common from "../common.mjs";

export default {
  ...common,
  key: "mysql-new-table",
  name: "New Table",
  description: "Emit new event when a new table is added to a database. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/select.html)",
  type: "source",
  version: "2.0.2",
  dedupe: "unique",
  props: {
    ...common.props,
    db: "$.service.db",
  },
  hooks: {
    async deploy() {
      const tables = await this.mysql.listTopTables({
        maxCount: 10,
      });
      this.iterateAndEmitEvents(tables);
      this._setLastResult(tables, "CREATE_TIME");
    },
  },
  methods: {
    ...common.methods,
    async listResults() {
      const lastResult = this._getLastResult();
      const tables = lastResult
        ? await this.mysql.listBaseTables({
          lastResult,
        })
        : await this.mysql.listTopTables({
          maxCount: 10,
        });
      this.iterateAndEmitEvents(tables);
      this._setLastResult(tables, "CREATE_TIME");
    },
    generateMeta({
      TABLE_NAME: tableName, CREATE_TIME: createTime,
    }) {
      return {
        id: tableName,
        summary: tableName,
        ts: Date.parse(createTime),
      };
    },
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
MySQL	`mysql`	`app`	This component uses the MySQL app.
	`timer`	`$.interface.timer`
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.

Trigger Authentication#

MySQL uses API keys for authentication. When you connect your MySQL account, Pipedream securely stores the keys so you can easily authenticate to MySQL APIs in both code and no-code steps.

Before you connect to your MySQL database from Pipedream, please make sure your database is either:

Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 3306), or
Accessible from a static IP that you've configured using a VPC in Pipedream, and enabled the workflow to connect through that VPC

SSL Setup

Configure SSL on your MySQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.

About MySQL#

MySQL is an open-source relational database management system.

Action#

Run Python Code on Python

Description:Write Python and use any of the 350k+ PyPi packages available. Refer to the [Pipedream Python docs](https://pipedream.com/docs/code/python) to learn more.

Python Overview#

Develop, run and deploy your Python code in Pipedream workflows. Integrate seamlessly between no-code steps, with connected accounts, or integrate Data Stores and manipulate files within a workflow.

This includes installing PyPI packages, within your code without having to manage a requirements.txt file or running pip.

Below is an example of using Python to access data from the trigger of the workflow, and sharing it with subsequent workflow steps:

Action Code#

import python from "../../python.app.mjs";

export default {
  name: "Run Python Code",
  version: "0.0.2",
  key: "python-run-python-code",
  description: "Write Python and use any of the 350k+ PyPi packages available. Refer to the [Pipedream Python docs](https://pipedream.com/docs/code/python) to learn more.",
  props: {
    python,
  },
  type: "action",
  methods: {},
  async run({
    steps, $,
  }) {
    // Placeholder action for Python code app
  },
};
