Read rows from Databricks

Used integrations:
class DatabricksSourceSelect {
async init() {
// TODO: Create your databricks credential
// More info at https://yepcode.io/docs/integrations/databricks/#credential-configuration
this.databricks = yepcode.integration.databricks(
"your-databricks-credential-name"
);
this.session = await this.databricks.openSession();
}

async fetch(publish, done) {
// TODO: Customize your sql query
// More info at: https://github.com/databricks/databricks-sql-nodejs/blob/main/tests/e2e/batched_fetch.test.js#L21
const queryOperation = await this.session.executeStatement(
`SELECT * FROM your_table_name`, {
runAsync: true
}
);
const results = await queryOperation.fetchAll();
await queryOperation.close();

for (const result of results) {
await publish(result);
}
done();
}

async close() {
await this.session.close();
await this.databricks.close();
}
}

Append CSV entries to Tinybird datasource

Used integrations:
class HttpTargetTinybirdAppendEndpoint {
async init() {
// TODO: Create your http credential with tynibird information:
// More info at https://yepcode.io/docs/integrations/http/#credential-configuration
// baseUrl: https://api.tinybird.co/v0
// HTTP Headers: { "Authorization": "Bearer your-read-token" }
this.httpClient = yepcode.integration.http(
"your-http-tinybird-credential-name"
);

// Transforms the items into a csv format
this.stringifier = csv.stringify({
delimiter: ",",
});
const targetStream = new PassThrough();
this.stringifier.pipe(targetStream);

// Append the stream to Tinybird endpoint
const formData = FormData();
formData.append("csv", targetStream);

// TODO: Customize your request checking the API documentation:
// https://www.tinybird.co/docs/api-reference/datasource-api.html
this.tinybirdPost = this.httpClient.post(
`/datasources?format=csv&mode=append&name=your_end_point_name`,
formData, {
headers: {
...formData.getHeaders(),
},
}
);
}

async consume(item) {
// TODO: Map item to your CSV format
const csvRow = [item.col1, item.col2, item.col3];
this.stringifier.write(csvRow);
}

async close() {
this.stringifier.end();
await this.tinybirdPost;
}
}

YepCode is a SaaS platform that enables the creation, execution and monitoring of integrations and automations using source code in a serverless environment.

We like to call it the Zapier for developers, since we bring all the agility and benefits of NoCode tools (avoid server provisioning, environment configuration, deployments,...), but with all the power of being able to use a programming language like JavaScript or Python.

These recipes are an excellent starting point for creating your own YepCode processes and solving complex integration and automation problems.

You only have to complete the sign up form and your account will be created with our FREE plan (no credit card required).

YepCode has been created with a clear enterprise focus, offering a multi-tenant environment, team management capabilities, high security and auditing standards, Identity Provider (IdP) integrations, and on-premise options. It serves as the Swiss army knife for engineering teams, especially those requiring the extraction or transmission of information to external systems. It excels in scenarios demanding flexibility and adaptability to change within the process.

Sure! You only need to configure YepCode servers to establish a connection with that service. Check our docs page to get more information.
